[horde] Database trouble after update to 5.2.1

[steffo76 at gmx.de]

Hi there,

after updating my horde installation to 5.2.1 I'm having a database problem concerning turba. After the update I'm experiencing some trouble with turba contact lists- trying to open them leads to a more or less blank screen and an error in the log saying

2014-09-02T14:55:49+02:00 ERR: HORDE [turba] SQL QUERY FAILED: Unknown column 'object_category' in 'field list'
        SELECT object_id, owner_id, object_type, object_members, object_uid,
          object_firstname, object_lastname, object_middlenames,
          object_nameprefix, object_namesuffix, object_alias, object_bday,
          object_anniversary, object_spouse, object_photo, object_phototype,
          object_homestreet, object_homepob, object_homecity,
          object_homeprovince, object_homepostalcode, object_homecountry,

          object_role, object_company, object_logo, object_logotype,

          object_pgppublickey, object_smimepublickey, object_imaddress,

          object_id IN ('013a7ce35400940be4dffx82242895dc') AND owner_id =
          'blablabla' [pid 2419 on line 258 of "/usr/share/pear/Horde/Db/Adapter/Mysql.php"]

Which is pretty much correct, considering:

Can I just say 

alter table turba_objects add column object_category varchar(80);

?
