strange error with python and mailman

[henk]

Hi all,

i'm getting a strange error with mailman and python since a couple of
days. Stupid thing is that i cannot reproduce it on other boxes with the
same setup. The box is a straith debian/woody install with python-base
1.5.2-16, mailman 2.0.6-1, libc6 2.2.3-9.

I'm not a programmer but hope somebody can help me....

grtz,
henk
