282405 - Crash if window is destroyed while executing onChange [@ g_type_check_instance_is_a]

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

[Mats Palmgren (inactive)]

Crash if window is destroyed while executing onChange.

STEPS TO REPRODUCE:
1. load attached testcase
2. follow instructions in testcase

ACTUAL RESULTS:
onChange handler is triggered - alert pops up, crash follows.

EXPECTED RESULTS:
onChange handler should not be triggered I think.

Reproducible: about 50% in the nightly build, less so in the debug build.

PLATFORMS & BUILDS TESTED:
Bug occurs in Mozilla nightly build GTK2+XFT 2005-02-08-03 trunk Linux.
Bug occurs in Linux -current debug build.

Bug does not seem to occur in GTK1 builds - the onChange handler is not
triggered. The type of form control is not important, I first saw it
using a <select onchange>.

That looks like a GTK widgetry issue....

Closing because no crash reported since 12 weeks.

Reopening because crash bugs **with testcases** should not be resolved **as WONTFIX** based on queries of crash-stats.  Other resolutions may be appropriate for other reasons.

(Crash signatures are not the same as bug identity; they're merely a search aid to find and group similar crashes.  The bug may still be present, but the signature may have changed slightly, or the bug may even still be present with the same signature but there are simply no recent reports of crashes in that function.)
