Several years ago Gustavo Carneiro posted a pygtk exception handler to
this list, which displayed a nice pygtk error dialogue.

I had modified it a few years back; and now put my version online. You
can find more info at my weblog:

Just download and run the module as an application for demonstration.

Please note; there are more modifications on the gtkexcepthook module
Gustavo wrote. Do an online search to find these.

Well, the above module will only be of any help if your code actually
fails because it generates an exception. If not, I'm not sure how to
figure out what's wrong.
Maybe running from within a Windows Python IDE could provide more insight.
