Analysis of TB17821431

[L. David Baron (dbaron)]

I believe these crashes are showing up in significant numbers on Windows as well (the clear reports are on Linux): although the only the first, fifth, and sixth, and eighth frames of the stack are identifiable. (I've seen stacks reliably mangled in similar ways for other crashes on Windows.)

don't know if it is of any use, but I like the links into LXR

Looks like this is missing 1.8.0.3, try 1.8.0.4

[Dveditz (dveditz)]

Minusing, no patch and a shutdown crash isn't critical enough to push hard for.

It's probably the same problem.

[L. David Baron (dbaron)]

A number of the user comments for this stack don't mention shutdown; they mention sites like gmail, google.com, etc. See:

[L. David Baron (dbaron)]

Actually, never mind the previous comment. The stacks are different; the ones not within XPCOM shutdown are destroying a wrapped native, not a wrapped native proto.

A windows user with incident - http://talkback-public.mozilla.org/search/start.jsp?search=2&type=iid&id=26109651 - reported that disabling an extension called "My Global Search" stopped the crashing on exit. Apparently it appeared automatically after installing BearShare, and uninstalling BearShare didn't remove the malware.

Thanks for your bug report. Could you please install firefox-dbg and try to obtain a backtrace (or crash report) by following the instructions on https://wiki.ubuntu.com/DebuggingFirefox This will greatly aid us in tracking down your problem.

Maybe linked to #74576

Which flash package do you have installed?
Which Java package do you have installed?
Which firefox extensions do you have installed?

Thanks
David

Stack trace for previously attached crash report with debug symbols (as provided by apport-retrace with the firefox 2.0+0dfsg-0ubuntu3 and debug symbols installed).

[Hilario J. Montoliu (hjmf) (hmontoliu)]

A couple of talkback reports with same stacktrace:

[Alexander Sack (asac)]

we haven't received any dupes for a while and in ffox 3 the code involved is different. closing this bug.

[Jruderman (jruderman)]

Very few of these crashes nowadays. It sounds like dbaron never identified a likely cause (except maybe the last paragraph of comment 0?).
