TBird 68.1 and gfx.downloadable_fonts.enabled (Linux)

[Woodsman]

Testing TB 68.1 on Linux. Old profile with many accounts. Attempting to launch TB caused a seg fault. Eventually I bubbled out the culprit:

gfx.downloadable_fonts.enabled=false

Removing from prefs.js or changing to true allows TB to launch.

Is this by design or a bug?

It is set to true by default in my TB 68.1.0 on Ubuntu 18.04.3 LTS.

Something must have changed it in your setup in the past. Possibly an extension.

Moved from Thunderbird Bugs to Thunderbird Support as you don't appear to be discussing workarounds for a reported bug (in Bugzilla).

A long time ago I manually changed the option to FALSE in my user.js file. I never had an issue with the change going back many versions of TBird. Upon testing 68.1 I discovered TBird would segfault with that option set to FALSE.

I am hoping this is a bug, but confirmation would be nice. I only rarely enable HTML in TBird to view emails, but I am uneasy if this setting is now hard-coded to TRUE. Hard-coding to TRUE would be contrary to traditional TBird design not to allow remote content in an HTML mail.
