maemo.org - Talk - GPE sync fails

I had set up a working sync with kitchensync between evolution and my n800 running gpe.

This week I get into troublle when I try to sync. I get the following error message:

Code:

Couldn't commit event. Not important malformed event Morgen 12.00 ((null)). lacks required field dtstart.

Followed by:

Code:

Unable to write one or more objects

How can I fix this? Thanks in advance!
