Bug 306114

I use Kolab 2.4 + zpush to sync between mobile and PC
When I create an Event on my mobile z-push service creates a Kolab (V2) compatible event on the imap server that is fine for e.g. the Horde web client or 4.8 Kontact (when there was no libkolab)
Now I use
libkolab.so.0.3.1 with Kontact 4.9.0
and every event created from zpush leads to an error message on the desktop.

The problem is that zpush creates encoded mail bodies while libkolab search for a special clear text XML header


Reproducible: Always

Steps to Reproduce:
1. Create an event on your mobile 
2. use active sync service + zpush to sync created event to server
3. Look in Webclient if event is there (-> Ok)
4. Resync Kontact folders
> Error about missing XML header
5. Look in Kontact Calendar for synced event (-> Missing)

Actual Results:  
No support for active synced data

Expected Results:  
support for active synced data
