TMDA-CGI Crash

Hi
    I have been trying to figure this error out now for three days. Could somebody please shed some light on it. I have several customers getting the following error almost every day. They always seem to be base64 errors.

Centos 3.8
qmail 1.03 + patches
python 2.5
tmda 1.0.3
tmda-cgi 0.13

The error is:

<class 'binascii.Error'> Python 2.5.1: /usr/local/bin/python

A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.

Ant help on this would be greatly appreciated
