This used to be an ASSERTION. See bugs #378836, #386211 and #386804. I compile cairo with debug symbols and installed the breakpoints. Is that of any help to you?

Attachment: stacktrace

Upon closing browser windows I get this reproducibly with current cvs HEAD build.

Comment 2

A clean Mac trunk Sunbird debug build outputs the following on shutdown:

WARNING: Fonts still alive while shutting down gfxFontCache: 'mFonts.Count() == 0', file ../../../dist/include/thebes/gfxFont.h, line 165

-> Should go into some component of Core.

[Benoit Girard (:BenWa)]

I can't reproduce on mac or linux. Please re-open with detailed STR.

Comment 4

[Jonathan Kew [:jfkthame]]

FWIW, I see this sporadically with debug Firefox builds, on various platforms, but I don't have any consistent STR. It typically seems to occur together with a bunch of messages about leaked chrome:// URLs, if I recall correctly.

[Benoit Girard (:BenWa)]

Alright, that's enough evidence to reopen.

Reproduced in Bughunter automated crash testing on Linux.

1. http://www.bvoltaire.fr/ in debug Nightly/53 build on Fedora 24/x86_64
2. Wait until page begins loading, then close browser by clicking on the window close (x).
3. Profit!

Note this occurs on Ubuntu and Fedora on Beta/51, Aurora/52, Nightly/53 and from this bug report from much earlier.
