(I'll ask you to bear with the somewhat vague description in advance -
I'm a noob in all respects here, with regard to python and the mailing

I'm getting some error reports sometimes when I quit a script, I've
been working on. The reports are extremely uninformative, and I do not
notice anything wrong in the script's behaviour, which makes the error
very hard to pin down. I'm therefore looking for advice on a way that
I can investigate the error.

Here's the deal. The script in question is a screen scraping thing
which downloads and parses the html in the background using a separate
thread (the 'thread' module), while the main program serves up the
data to the user, allowing some modicum of interaction. Sometimes, not
always (though I cannot see a pattern), when I quit the script, the
following error message is printed:

    Unhandled exception in thread started by
    Error in sys.excepthook:

    Original exception was:

And that's it! Seems like there's some information missing? What is
the error in sys.excepthook? What was the original exception? And

Any suggestions on how to proceed?
