Thank you for your bug report. I'm marking this as triaged as you also reported this upstream. If you report bugs upstream, it's not necessary to also report them in Launchpad.

Adding myself to cc

reporter: afaict the report is missing symbols for libxul, which makes it useless.

#6 0x00007f9c552ddd40 in GkAtoms_info ()
   from /usr/lib/xulrunner-1.9/libxul.so
No symbol table info available.

reinout: please don't comment when you add yourself to the cc list.

Hm. Debugging symbols are definitely present--they have been picked up for the other stack frames.

Please observe the stack traces of some of the duplicates of this bug (tracked at <http://bugzilla.gnome.org/show_bug.cgi?id=509083>). None of them have symbols for the GKAtoms_info frame, some don't have the frame at all, but are otherwise identical; see these for examples:

use comptr locally

The HASPENDINGEVENTS macro is ugly and IMO unnecessary. Use an inline function if you need to.

use inline

i just wanted to make sure people didn't accidentally change just one part

Why is the if (!thread) test changed into if (thread) ? It looks wrong.

patch applied to debian package

FWIW, I applied this patch to the debian xulrunner package, which should also fix this issue.

Could the patch from comment #9 be reviewed please? Thanks!

patch applied to debian package

This patch makes no sense. If "current" is non-null, how could "thread" possibly end up null?

i will land my patch (w/ the typo fixed) if i can ever find a green period for the tree.

Mike: I'm still seeing this on Debian systems, with xulrunner-1.9 version installed. So the patch does not seem to work.

timeless, what's the typo? thread instead of !thread? Would like to get this landed.

timeless e-mailed me with "yeah, that's the typo."

For future note, please comment in the bug rather than e-mailing me. E-mail gets lost and forgotten while bug comments are forever.

without the typo

Fixed patch

timeless: attach the patch you want checked in, mark everything else obsolete, add the checkin-needed keyword. kthxbye.
