Sorry no.
I don't know.
How can I finger out  whether or not I have two different installations?
Maybe there is something odd with this python installation.

I allways use /usr/bin/python.
There is a second binary called /usr/bin/python2.2.
But a diff shows me that there are no differences between this two

I installed everything on my system religious from Mandrake RPMs.
Only Mailman itself and the MTA (Exim) where build manually.

I will try to analyse this on my system a little bit better.
I will do some mailman independent tests.

The python version is 2.2.2.
Here is what python -v shows:

Python 2.2.2 (#2, Feb  5 2003, 10:40:08)

The OS is Mandrake Linux 9.1 with the newest updates.
I used the Mandrake update process (urpmi).
So I shouldn't be the only one who has this problem.

Meanwhile I think it is likely more a Mandrake/Python
issue than a mailman topic.

All the same, I'am glad about every helpful suggestion.
Many thanks!
