Do you get any kind of error message when your application crashes?

I'm suspecting this probably has something to do with the slightly weird
reference counting with exceptions.  In addition, you're supposed to use
sys.exc_info() because it's thread-safe.

Here's some code that will extract a safe string from the exception that
you should then be able to pass into your MessageBox:

import sys, traceback
try:
  ....
except:
  s = apply ( traceback.format_exception, sys.exc_info() )
  pos.alert(s)
