The above stacktrace is from a 4/28 build. The crash (segv) happens in
#0 nsEnderEventListener::DispatchMouseEvent ()
#1 nsEnderEventListener::MouseDown ()
Changing summary to include nsEnderEventListener.
Adding testcase keyword.
Changing component to Event Handling, reassigning to akkana (owner of
bug 28401 "Double mouse click events: rewrite nsEnderEventListener").

Mike is landing code in a few days (if he hasn't already) that completely
eliminates this class, as I understand it. Is this blocking anyone right now?
I'd rather wait and see if the problem still happens with Mike's code.

Marking dependency on the stuff Mike is working on. When that's in, I'll check
this and see if the crash still happens.

Mike has his ender lite stuff (34896) just about ready to go, and several of us
are testing it. But I can't reproduce the crash on my linux build even in a
standard non-ender-lite build. I've tried clicking in the text widget, then
outside it in the content area, back in the text widget, outside it in the
urlbar, back in the widget, etc. No crashes.
Is anyone still seeing this? Please retest and see if it's still happening, and
if so, let me know what I'm doing wrong in trying to reproduce it.

Re-tested on PC/Linux. 2000051308 crashes, but 2000051520 works for me.
2000051712 is fine, too. Some noticable changes between 5/13 and 5/15 are
that the curser changes to I-beam on mouseover the input text field now,
and there are some messages appearing on the console when clicking in the
unused content area:
no handler found for HTML
But the crash seems to be gone. Recommend WORKSFORME.
BTW, I really love the new speed :-). Go, mozzy, go!

Adding keyword to bugs which already show a nsbeta2 triage value in the status
whiteboard so the queries don't get screwed up.
