Comment 2

[Edward Kandrot]

I need help from a Mac person to track this down.  Is it a common problem, or a
known issue?  Is there any talkback data for this crash on any other platforms?

Comment 3

[greer]

This may be related to a crash that is happening on NT at startup:

One comment looks as though the problem nay have happened at some point other 
than startup:

jband was just working on |GetNewOrUsedProxy|, I think.  I recall some email
going by about that... perhaps he can weigh in with some knowledge.  His changes
might not even be in the build that's having this bad behavior, but he has good
knowledge that may help greatly in understanding the problem.

scc: I haven't touched this code. You're maybe thinking of a similarly named 
method in xpconnect (upon which dougt based this code).

The line in the stack...

http://lxr.mozilla.org/seamonkey/source/xpcom/proxy/src/nsProxyEventObject.cpp#1
72

...Is in the middle of a comment before an assert with specific instructions to 
ask dougt:

    If you are hitting any of the assertions in this block of code, 
    please contact [e-mail].

Adding him to the cc list.

[Doug Turner (:dougt)]

this is a dup of 74057.  I have had considerable trouble reproducing this.  if
anyone can reproduce this reliably, please let me know.  

Marking this as a dup.
