29694 - Crash on close mailnews while waiting for password entry

Status: VERIFIED DUPLICATE of bug 26926

(SeaMonkey :: MailNews: Message Display, defect, P3)

Description

[a-huntwork]

Observed on clobber build pulled and built 2-27, linux rh 6.1.

To replicate:
Set mailnews to startup with browser.  Don't allow password to be saved. 
Restart moz.  When mailnews starts, it asks for a password.  Instead of entering
a password, close the mailnews window, then hit the cancel button on the
password window.  Moz gets segfault.  Here's the stack trace:

Confirmed on Linux build 2000.03.01.08.  Also happens when you load Mozilla
browser only, open Mailnews, close Mailnews, open Mailnews again, then proceed
with steps to reproduce.

I can't reproduce using the 3/1 build on NT. Same stack trace as bug 26926

Using linux build 2000-03-01-13, I tried the original scenario.  However, in 
readidng the scenario where it says to "Set mailnews to startup with browser" I 
assume this means to change the Appearance Preference setting to "On startup 
launch," = Messenger.  This would make the mailnews window the only one opened 
and when closing it all that's left is the password dialog.  In this case, I 
crash ever time when clicking Cancel in the Password dialog. 
  
In the zach's case where the Browser is opened first, open and close mail twice, 
then press Cancel in the password dialog I crash every time too.

In the case where Browser is opened first, and you open mail only once and close 
it, then press Cancel in the password dialog, I only crash 50% of the time.  
Sometimes the Browser window stays opened and I can go to mail and log in and 
use it.  Because duplicate bug 26926 is about random crashes opening and closing 
windows this scenario should be tested when that is fixed.
