Looking at stderr, it looks like this may not be a view/widget bug:

title string = [Mail - Mozilla]
title string = [Mozilla]

I'll let you reassign as appropriate.

Comment 2

[Dan Mosedale (:dmosedale, :dmose)]

Though it seems like an uncaught JS exception still shouldn't be causing a
segfault.

Comment 3

[Patrick C. Beard]

This isn't a view manager bug, and nsViewManager2.cpp isn't part of the current 
building tree.

Comment 4

[vidur (gone)]

Dude, you've got to give me a bit more to work with here. The crash doesn't seem 
to be a direct result of the exception thrown (there's more stuff printed out to 
the console after the exception string). Bringing up mail and news works fine 
for me on Windows and Linux debug builds. If this is an optimized build issue on 
Linux, it's possible that it's related to the platform-specific timer 
implementation. 

Either way, I can't recreate it on the builds I have and I'm going to mark it 
WORKSFORME. If you can recreate it on an optimized Linux build, I'd suggest 
reopening and starting with either someone on the mail team (to deal with the 
exception) or one of the Linux-heads.

Comment 5

[Prashant Desale]

I can't reproduce it either.
