(bottommost toolbar) causes apprunner to crash.

Steps to Reproduce:
1) Launch apprunner
2) Click once or sometiems several times on 'Mozilla'
3) Crash.

Actual Results:
My linux box gives a Gtk-WARNING **: invalid cast from (NULL) pointer to
'GtkWidget' just before dying.

Expected Results:
Don't know the spec on this but at the very least a XUL popup with maybe
some relevant mozilla links. Definitely not hte crash though.

Additional Information:
the bug is highly reproducable but I have not been able to generate a
stack trace yet due to other diffuculties (talkback, gdb)

Probably a dup of the one I reported recently, but without involving another
menu already open. Were you really ever able to crash with one click?
reassigning to saari.

on windows and linux a mouseover yeilds:
JavaScript Error: TypeError: tipElement has no properties
URL: file:///D:/the directory seamonkey is in/chrome/navigator/content/
default/tooltip.js

At this point one click on linux will crash you with the above Gtk WARNING
on Windows(NT) it's only reproducing haphazardly.
