You can overwrite the sys.exepthook() with your own function:


import sys
from traceback import format_exception

def my_excepthook(exctype, value, traceback):
    details = "".join(format_exception(exctype, value, traceback))
    # now show the details in your dialog box

sys.excepthook = my_excepthook


See the documentation for details:

Hope this helps,
