[Mailman-Users] Mailman archive creation problem

[Limperis Antonis]

Hello mailman users

We have a mailman version 2.1.22 installation.
We try to reconstruct a mail  list archive with command 'arch --wipe listname'  and receive the following error.

#00000 <F60795D9B7521C478F6F9174A9183DC94279D62D at MAIL.cti.gr>

Traceback (most recent call last):

    archiver.processUnixMailbox(fp, start, end)
  File "/var/mailman/Mailman/Archiver/pipermail.py", line 596, in processUnixMailbox

Is there some  suggestion  or  experience on this problem?

Thank you, for your attention.
