17897 - crash giving focus to mail window

Status: VERIFIED INVALID

(MailNews Core :: Backend, defect, P3)

Description

[David :Bienvenu]

If I perform the following steps, I crash:

1. Open mail/news
2. Read two local mail messages
3. Bring another window forward (e.g., the console window)
4. Bring mail/news forward

I crash with the following stack:

Lisa, can you reproduce this? DP, I have no idea who's bug it is, but it seems
web shell/chrome related. I'm pulling a complete new tree to see if this problem
goes away, but I doubt it will. m_chromeElement is not deleted, but it does have
a vtable with fdfdfdf's in it.

Will try to reproduce this.

[David :Bienvenu]

thanks, Lisa. People actually pay attention to you! Me, everyone just ignores
until someone else has the same problem (not you, DP)

David, both Laurel and I cannot reproduce this problem in today's release build.
We are supposedly going to get a respin with alecf's fix later today so we can
try then also.  What does your window look like?  Is your sidebar/folders open
or closed?

[David :Bienvenu]

OK, pulled a whole new tree and this problem went away. Thank goodness.
