Firefox crashes in gtk dialog
Last modified: 2008-05-29 09:32:55 EDT
Firefox crashes when it tries to open a new GTK dialog. The crash is inside GTK.

The crash in the bt for comment #2 seems likely to be the null callback_data in
a call to moz_container_forall() as mentioned in
That suggested patch just adds a trivial check on callback_data before
attempting to walk the moz_container->children calling their widget callbacks...
Yes, I think so. There are many dupes for that bug on web:

possible patch for crash in comment 2
From the http://bugs.activestate.com/show_bug.cgi?id=64037 just so a copy is
here too. Adding that to firefox-220.127.116.11-11 (and it applies to thunderbird
too!) certainly seems to help reduce a number of crashes here...
I've not yet tested it with the other patches added in firefox-18.104.22.168-13
(personally I don't use firefox but many of our users here seem to...)
I'm currently rebuilding our test version of ffox to include the extra two
patches from your firefox-22.214.171.124-13 srpm as well as the gtk fix above. If all
goes well I plan to push that out to about ~400 machines here in the next few
days. I'll let you know how that goes.
The tests with just adding the gtk-fix seem to have reduced the number of
crashes quite a lot and the remaining ones *mostly* seem to be related to sites
using lots of annoying flash animations (like 6 adverts on one page all
competing for your attention...)
Long (long*) ago the flash plugin was so buggy that we didn't enable it by
default, and had to provide a wrapper which allowed people to turn it on for
sites which needed it. I hope we don't need to go back to that... :-(
Well as promised I'm including an update.
I'd like to confirm that the extra patch seems to help though we were still
getting a few crashes. As of friday we are using a version based on the new
security update firefox-126.96.36.199-14 with this (and the empty-doc) patch with no
obvious ill effects.
Most of the remaining crashes *seem* to be inside the flash plugin, though
obviously we havn't been running the new version for long enough to be really sure.
Though the fix isn't a good fix, as admitted in the activestate bug...
It defeats legitimate callbacks, so we need to find a better fix here.
The bug is in GTK and a fix is available (see
So it should be fixed in GTK.
That is certainly *a* bug in GTK with a fix available - which should obviously
be fixed in GTK.
Since the discussion in there seems to be related to problems with re-parenting
an object when it is dragged in a notebook it isn't entirely obvious that this
is the bug which is causing ffox (and tbird etc) to crash - or at least not
obviously the *only* bug...
The cited GTK+ change can _not_ fix any firefox crash in RHEL5 - for the simple
reason that there is not notebook tab DND in the GTK+ thats shipped with RHEL5.
Hopefully fixed by the RHEL-5.2 update. Please reopen if not.
