Illegal operation in Windows Media Player WMP plugin

Illegal Operation in Plugin

Windows Media Player Plug-in Dynamic Link Library
The plugin performed an illegal operation. You are strongly advised to restart Navigator.

This can be caused by having JavaScript disabled. To enable JavaScript:

* Firefox: Click "Tools → Options → Content (or Web Features) → Enable JavaScript".
* Mozilla Suite: Click "Edit → Preferences → Advanced → Scripts & Plug-ins → Enable JavaScript for → Navigator"

Make sure that any extensions you might have that can block JavaScript are not blocking the site in question or are disabled. These include NoScript and Adblock Plus.

That is what it says, but that no longer seems to be the case.
Has anyone else noticed that?

I no longer receive the error message, nor the crash that would normally follow shortly thereafter.
This is on the latest 1.8.1's (1.1a) where I have noticed this.

With JavaScript disabled, via NoScript, & Adblock Plus enabled, the following link, with a 1.1a build of 7-17-2006, would generate the Illegal Operation message. With a 1.1a build of 8-20-2006, that no longer occurs :smile:

I tried the URL with the 1.5a nightly of 20060817. SM started to crash and I got the crash reporter. Instead of crashing, though, SM went to 99% CPU utilization and I had to kill it. Downloaded the 20060820 nightly and got the error pop-up you refer to, but no crash. JavaScript is enabled and I don't think any of the one or two extensions I have would be a problem.

"20060820 nightly"

Is that the 1.5a (Trunk, I guess that is) or the 1.1a (Build, perhaps)?
I'm using the 1.1a's.

I have seen this "fixed" on two different computers now.

Ok, I've just downloaded a ZIP build of this:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060822 SeaMonkey/1.5a

Running it from this script:

Code: Select all

@echo off
set MOZ_NO_REMOTE=1
start "" ".\seamonkey.exe" -p "dumy"
set MOZ_NO_REMOTE=0

with JavaScript enabled, & I'm not sure what else may be affecting things ("dumy" is an existing, albiet clean Profile), but I get the Illegal operation message when I open the above link.

My regular install version:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1b2) Gecko/20060821 SeaMonkey/1.1a
does not generate any error message.

One up (a huge one up, in my book) for 1.1a over 1.5a - at this point.

I just took a look again at the URL in your initial post. This time I'm using

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060821 SeaMonkey/1.5a

on my home PC. No error message, and the video is playing just fine. I'll have to try it on the office machine tomorrow. Wonder if there's some difference in how they're configured. Or else the problem got fixed.

BTW, that's some video.

Initially I was thinking that this may have coincided with that one plugin bug that caused the quick release of SM 1.0.4 right after SM 1.0.3, but before I got to reading that bug, I came across the following:

Windows Media Player Dynamic Plugin Crash Regression, & in there is a comment, that "... I don't seem to be having this issue as of last nights build. Was whatever caused this backed out?"

WMP+JavaScript crashes of various sorts have been around for ages, & it would be great if this is resolved, even if inadvertently.

I tried your filecabi.net link in SeaMonkey 1.5a at work. It's the nightly of 20060822. I got the "illegal operation" message popping up. So, either there's some difference in the 20060822 and 20060821 nightlies, or there's some difference in the configuration of SeaMonkey on my two PCs.

I just tried the 20060823 nightly for SM1.5a on my home PC. While the 20060821 nightly played the video with no complaint, this one popped up the illegal operation error, but it continued to play the video. This was immediately after installing the nightly without a restart. I closed and restarted SM, and played the video again. SM crashed.

Not that I had seen the bug (crashes) when I initially posted this message, with earlier versions/builds, I had seen the referenced crashes regularly. (And that surprising change, no longer seeing it, is what prompted my initial post).

Anyhow, it is now marked as, "Fixed on 1.8.1 branch". (And by virtue of that, may still be an issue on the trunk).

Two thumbs up. Or as Andy shows, peace.

This appears to have regressed.
(Note, that I am only speaking of the 1.8.1 branch (1.1b) on Windows XP).

The last version that I have found that works correctly is the build of 20060919.

Now marked as ...

approved for 1.8.0 branch, a=dveditz for drivers

------- Comment #66 From Boris Zbarsky 2006-11-27 14:32 PST [reply] -------

Fixed for 1.8.0.9

Though I downloaded SeaMonkey 1.0.6 (1.8.0.9pre) 20061128 & it still errored

.
Ditto for SeaMonkey 1.1b from yesterday, 20061127.
And Firefox 2.0.0.1pre 1.8.1.1pre 20061128.

I'll see what turns up tomorrow.

EDIT:
Still not working in todays (20061129) 1.1b nor 1.06 builds.

Still not working in todays (20061129) 1.1b nor 1.06 builds.

Should it be?
Am I a day or so early - still?
Or is what I'm seeing different altogether from the bug itself?

I usually use SM 1.5a and I haven't seen any problems for quite some time now. I just installed SM 1.0.6 on a machine that had had Netscape 7.2 on it. Using an old NS profile with the new SM 1.0.6 installation, I had no problems playing the filecabi.net clip.

But did you have JavaScript disabled?
Edit | Preferences | Advanced | -> Scripts & Plug-ins

A better link to try:
http://gorillamask.net/fgfbomb.shtml

Gorrillamask does not do a check to see if JavaScript is enabled in your browser.

FileCabi.net now states, "You need to Enable Javascript to View this Video".
Not sure if it was the same when I posted the earlier link? Also note, with FileCabi.net, you would need to view the WMP & not the Flash version of the movie.

I checked again, making sure that JavaScript was disabled. Using SM 1.0.6 at gorillamask.net I got the "illegal operation" error. No problem with SM 1.5a, even with JS disabled.
