You can easily do it, just adapt the following to your situtation.  This is 
actually something that Greg Fortune (also on the list) wrote for our 
projects:

def handle_error(t, val, tb):
    import traceback
    import string
    msg =  '-----------------------------------------------------\n'
    msg += 'Traceback:\n'
    msg += string.join(traceback.format_tb(tb), '') + '\n'
    msg += '%s: %s\n' % (str(t), str(val))
    msg += '-----------------------------------------------------\n'
    print msg

    import ...backend.db as db
    if(db.is_connected()):
        import ...backend.Error as Error
        e = Error.Error()
        e.set_error(msg)
        e.submit()

sys.excepthook = handle_error

Of course, make sure qt fully works before you uproot sys.excepthook.
