91127 - Crash after dismissing security dialog

Status: VERIFIED DUPLICATE of bug 89626

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Terry Hayes]

The browser crashes when attempting to access the secure login page.  When the
"login" button is clicked on the main page, the browser displays a security
warning ("entering a secure site").  In cases where content is already loading
from the site, this works.  However, when no content from the login page has
been displayed yet dismissing the dialog window causes a crash.  This is timing
sensitive: I would say that 50% of attempts fail on my laptop running NT.

Turning off the security dialog prevents the problem from occurring.

To reproduce:
1) Make sure that the "entering" warning is on.  (Prefs/SSL panel)
2) Go to www.schwab.com
3) Click the "login" link or arrow at the top right.

Two possible results:
1) The page starts to load (typically the top half is displayed), then the
warning dialog appears.  Dismiss the dialog and the page loads normally.
2) The dialog appears before any of the login page content is displayed. 
Dismiss the dialog, causing the crash.

Is this happening on the daily 0.9.2 branch builds?

Comment 3

yes, reproduced on the 0715 N6 branch build (from the FTP site)

I can't reproduce with my debug build. I'm doing a fresh pull and build to see 
if that helps.

As I said, this appears to be timing sensitive.  A slower processor may be
required to slow the start of the content display.  Maybe a loop added to the
processing in the layout component would help reproduce this.

Have you looked at the talkback trace to see if that give any clues?  I'll
attach a stack trace as well.

This is just yet another variant of bug 80203.  If the pres shell lasts longer
than the doc viewer, we're in trouble.
