Already fixed in Git.

After editing an existing contact (DB backend), I am not able to save 
changes. Turba reports following error message:

- There was an error saving the contact. Contact your system 
administrator for further help.

It seems it's related to "horde categories":
- If I choose "New Category" instead of an existing category name, the 
saving is successful.

If I look at turba/lib/Driver/Sql.php _save() function, the error may 
be related to this hash:

$attributes['object_category'] => Array ( [new] => , [value] => WORK) ;

This attribute is an array and not a single string.
