You can also use this code *before* you import gtk:

import os

os.environ['PYGTK_FATAL_EXCEPTIONS'] = '1'

(for some reason, os.putenv() doesn't work).

I'm currently working on a patch for pygtk-0.6.5 which will call
a user-callback in case of an error. That would allow to open a
window with a trace instead of silently dying.
