21884 - [dogfood] crash visiting various websites in the image / networking code

Status: CLOSED FIXED

Description

[Scott MacGregor]

This started showing up in the builds tonight (12/15). I see it when loading
phonebook. Other people see it visiting various websites.

We crash because lib container has been deleted and we are getting an On data
available call that causes image lib to try to use this deleted container in
IL_StreamWriteReady.

I started seein this right after I pulled Rick's changes to http tonight. So I'm
wondering if that may be related.

Okay, I backed out Rick's checkin from tonight and that fixed the crash. Chris
H. wanted me to back out Rick's checkins if we can't reach him tonight.

Rick, I backed out your changes tonight to fix the crashing problem. I'll
re-assign this to you. I suppose you could mark this fixed and then re-open the
original bug you were fixing?

orignal bug fix that appears to have caused this regression was
http://bugzilla.mozilla.org/show_bug.cgi?id=21459

[rpotts (gone)]

So, I've fixed the changes for bug #21459 to prevent this crash :-)
I've just checked in the changes again...
