349288 - Crash [@ 0x00000000] [@ nsCSSFrameConstructor::AdjustParentFrame] [c:/builds/tinderbox/Fx-Mozilla1.8.0-Release/WINNT_5.2_Depend/mozilla/layout/base/nsCSSFrameConstructor.cpp, line 3470]

Status: RESOLVED INCOMPLETE

(Core :: Layout, defect)

Description

[Alex Vincent [:WeirdAl]]

Talkback ID: TB22253222Y

The line in question indicates aChildContent was somehow null.

http://lxr.mozilla.org/seamonkey/source/layout/base/nsCSSFrameConstructor.cpp#3548 indicates the code has not changed on trunk.

cc'ing bz as cvs blame points to him for the line that crashed.

Steps to reproduce:
(1) Attempt to load chrome://mozapps/content/update/updates.xul in Firefox.
(2) If at first you don't succeed, try again.

I have not tried to reproduce this.  Expected results:  don't crash :)

Need reliable steps to reproduce; not likely to go anywhere without those.

Unfortunately, when I try to repro it by loading the URL again, it just closes tabs on me.

Alex, does chrome://mozapps/content/update/updates.xul still exist?

Alex in comment #4:

but it doesn't crash for you?

Reloading chrome://mozapps/content/update/updates.xul furiously in Firefox trunk did not result in a crash.  Tested on Windows Vista.
