mailman cronjobs under jaguar 10.2

I've got a weird problem with my mailman installation running with postfix on a G4 with Jag server 10.2. every time the qrunner python script starts it delivers the same error message in /mailman/logs/error. The queued messages (the ones in qfiles) didn't deliver. What can i do? I do not know Python (who does?). Please, any suggestions? The log ooks like this: Jan 15 15:41:00 2003 qrunner(2816): Traceback (most recent call last): Jan 15 15:41:00 2003 qrunner(2816): File "/home/mailman/cron/qrunner", line 283, in ?
