[Mailman-Users] Problem with config.pck

[Markus Schanovsky]

Hello!

I am very sorry to ask for help, but I run into a big problem with 
mailman 2.18.
Everytime I try to call an admin-pages of mailman or a user calls his 
personal admittance to his mailman-subscription I get the following 
error-message:


==============
Bug in Mailman version 2.1.8





We're sorry, we hit a bug!

If you would like to help us identify the problem, please email a 
copy of this page to the webmaster for this site with a description 
of what happened. Thanks!


Traceback:


Traceback (most recent call last):

======================================================

The rights for the files are:
-rw-rw----  1 mailman  mailman  1867148 May 19 22:08 config.pck
-rw-rw----  1 mailman  mailman  1867148 May 19 22:08 config.pck.last
-rwxrwxrwx  1 www      mailman      823 May 19 16:52 pending.pck
-rwxrwxrwx  1 www      mailman      665 May 19 11:57 request.pck

Every time I change the permission to 777 I can reach the 
admin-pages, but if mailman is running (mailman.sh start) the 
permissions are quickly set back to the version You see above.
Regardles who I set as owner:group - everytime the same effect.

Now my question:
Who is setting the file-permissions back?
Who shall be the correct owner?
What can I do?

With best regards fram Vienna
