ActiveSync: Error after upgrading to Kolab 3.1

[Tobias Brunner]

Hi,

I've upgraded from Kolab 3.0 to 3.1 on Debian Wheezy. It looks like 
there were changes to ActiveSync, because syncing with my Nokia N9 does 
not work anymore. Looking at the debug log on the Nokia N9 shows the 
following error:

[Error] AS_LIB : Wrong response content type  (expected: 
application/vnd.ms-sync.wbxml or application/vnd.ms-sync.multipart)

The activesync log on Kolab looks like this:

Any idea what could be wrong?
