This fix wont work. Users who have no additional folders are no able  
to log in. But existing folders wont be shown anymore.

I have the same problem with the current horde groupware edition. One  
of my users is complaining about this problem and I tried this patch.  
Now the user is able to log in. But if I log in to my account, I can  
only see my inbox, no additional folders. If I remove the patch, all  
folders are shown again.
