[newgroups] error after join

[Robert Jäschke]

After filling out the form on http://newgroups.biblicious.org/joinGroup?group=wurstgruppe I am redirected to http://newgroups.biblicious.org/joinGroup and get the error message Internal Server Error: java.lang.RuntimeException: User is not a member of this group.
