[turba] Autocomplete does not work with 3.0.12

[Mehmet Giritli]

I am using a ldap backend addressbook and autocomplete with new message
composition's To field does not work. I can see that a query is made to
the ldap server, but no results are displayed by Turba.

I found bug http://bugs.horde.org/ticket/10961 which looked very similar
to my issue, except that I am using a ldap backend. I see that 3.0.12
included the fix for it, but I still have the problem. Could it be that
the problem is not entirely fixed?
