What does asterisk mean in Inbox (*12)

[ninjagranny]

I have to admit I just upgraded to 38.4 and got this damn asterix too - wish i could roll back 1 version

I have 11 imap accounts and it only appears on one and disappears if i collapse the child folders - its highly annoying . I don't even have any unread in any child folders on that account and its damn annoying that it totals all child folders and not just the inbox

What I did t minimize that was:
- Unubscribed all the folders I do not need or use, like "All Mail" or "Starred" on GMail;
- Marked as read all emails I had laying around.

This is not a solution, but solved a part of the problem.

Any information on whether this bug will ever get fixed, or should I stick with setting the following to false:

mail.folderpane.sumSubfolders
