le dahut: I'm not sure which bit is wrong. I could
point out that traceback.print_exc () will *print*
the current exception (to stdout / stderr, not sure)
and *return* None, so your line:

   logging.debug('Error %s'%traceback.print_exc())

probably doesn't do what you want, as it will
log the string "Error None". But this may be no
more than incidental to your issue.

The fact that you're getting "logon.exe.log" suggests to me that
you're using py2exe, which has its own setup for trapping
traceback and things which go to stdout. Is this the case?

Hopefully someone else can see more clearly than I am, but
if they can't, you're going to have to come up with a *really*
small example of what does or doesn't work.
