[Mailman-Users] Stange error with mailman

[Simone Lupi]

Hi,
I'm really new to this software and i've installed it. It seems to work fine, sends the test mail, but the web interface gives to me this strange error:

Traceback:

Traceback (innermost last):
  File "/home/mailman/scripts/driver", line 89, in run_main
    main()
  File "/home/mailman/Mailman/Cgi/admin.py", line 68, in main
    mlist = MailList.MailList(listname)
  File "/home/mailman/Mailman/MailList.py", line 69, in __init__
    self.Load()
  File "/home/mailman/Mailman/MailList.py", line 858, in Load
    self.Lock()
  File "/home/mailman/Mailman/MailList.py", line 1300, in Lock
    self.__lock.lock()
  File "/home/mailman/Mailman/LockFile.py", line 209, in lock
    os.link(self.__lockfile, self.__tmpfname)
OSError: [Errno 1] Operation not permitted

On what depends? Not that i'm trying to work with mailman + apache in a chroot enviroment. Any suggestion would be appreciated.
Cheers,
Simone.
