I experience this too, but it might be a bug in Gtk+ 2.2.1 (which I am 
using).

Here's my gdb session with Emacs:

If neccessary, I can provide more details and complete trace.

This time, it took me some 5--10 minutes of loading various modes 
(c-mode, sgml-mode, po-mode, lisp-mode, and finally w3m with unicode 
support, it might have loaded also un-define), and monstrous clicking on 
the menus (which I don't actually use, so this is not a big issue for 
me, I actually noticed it only when raising window using a click but 
still wanting to keep the point at the position it was at).


This is from report-emacs-bug:
