255909 - somewhat repeatable crash / hang regression in 0.9.3 when switching between multiple loading tabs [@ nsEventStateManager::GetPrevDocShell ]

Status: RESOLVED DUPLICATE of bug 162283

(Firefox :: General, defect)

Description

[Marc Bejarano]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3

ever since i installed 0.9.3, i've been having crashes and hangs when i quickly
switch back and forth between multiple browser tabs that are loading images
using the ctrl-tab and ctrl-shift-tab keyboard shortcuts.

talkback ids:
TB579127H, TB535971W, TB531217Y

i never saw this with 0.9.2 or earlier, so i think this must be a recent
regression.  if the talkbacks aren't enough to isolate the issue, i can try
downloading nightlies to narrow down exactly when the bug was checked in.  i've
gotten pretty good at getting firefox to crash with this bug ;)

Does this crash also occur with a nightly branch build?
ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-0.9/

Uninstall 0.9.3 and then try the nightly, you might also try a new profile.
