Description:
------------
All of a sudden, mlmmj doesn't handle the +list alias properly anymore and crashes. It worked so far, and I rebooted the machine to avoid old libraries in RAM making trouble, to no avail. Any other + command (like +subscribe) works, and mlmmj-list on the command line does so as well.

The output sent back is:

 Command died
    with signal 6: "/usr/bin/mlmmj-recieve". Command output: *** glibc detected
