[Dovecot] Crash on malformed ldap user_filter

[Anders]

I did a little too much copy/paste, and ended up with an ldap config
file containing a line of the form

  user_filter = user_filter = (&objectClass=...

(with "user_filter =" repeated). This caused the auth process to
segfault (v1.1.rc1). I suppose that I can reproduce this problem if
more information is needed.
