I tried to sync an kalendar with lightning. I discovered exceptions  
from recurring events are not synchronized correctly (see  
http://article.gmane.org/gmane.comp.horde.kronolith/4988/)

Now I made a sniff:

result is: in kronolith there are no changes and after reloading the  
calendar in lightning, the exception will flush.


Now I tried the following:
Importing the iCal manually, Lightning tried to send to the webserver.  
The results here become still stranger.
In Kronolith the exception will be displayed, but the belonging  
recurring event ("serientermin") is not visible, any more.
In Lightning instead (after reloading) the recurring event is  
displayed, but the exception not.
