Hi,

Kolab uses IMAP annotations to specify the content of a folder. It's  
stored in the "folder-type" annotation. This folder type can be  
"event, task" and others.

There can also be a suffix of ".default", which indicates this should  
be the default folder for this content type.

Right now Horde dies with a "fatal error" if there are two or more  
folders with the ".default" annotation. If this error is on a folder  
shared to all users, Horde will no longer work for all users.

The exception looks like this:
2012-07-19T16:59:39+02:00 ERR: HORDE [mnemo] Both folders  
user/groupware/Kalender and user/groupware/Kalender/IGC-Kalender are  
marked as default folder of type event! [pid 24440 on line 366 of  
"/datastore/DEVEL/horde/framework/Kolab_Storage/lib/Horde/Kolab/Storage/List/Query/List/Cache.php"]
2012-07-19T16:59:39+02:00 EMERG: HORDE [horde] exception  
'Horde_Kolab_Storage_Exception' with message 'Both folders  
user/groupware/Kalender and user/groupware/Kalender/IGC-Kalender are  
marked as default folder of type event!' in  
/datastore/DEVEL/horde/framework/Kolab_Storage/lib/Horde/Kolab/Storage/List/Query/List/Cache.php:366

The same check is in  
Kolab_Storage/lib/Horde/Kolab/Storage/List/Query/List/Cache.php and  
Kolab_Storage/lib/Horde/Kolab/Storage/List/Query/List/Base.php.

-> It would be much better to present one of those fancy popup error  
messages. The user can continue to work and the admin still gets  
notified to fix this.
