Calendar Entries synced from IMAP to phone are non editable (Calendar app crashes)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set up an appointment on the PC, sync it to IMAP
2. Sync appointment to phone
3. It shows up correctly in the calendar
4. One can long press on it and select "view"
5. However, one CAN NOT edit it -> Calendar app crashes.

What is the expected output? What do you see instead?

Calendar app opening the edit window

I have had a look on the sqlite db but cannot tell whats exact difference 
between events created from phone in our calendar via calendar app, which are 
then editable, and appointments synced to the phone.

I just noticed that there are differences in "hasExtentedProperties" and also 
our timezones seem to have issues (see issue #73)

The Android build in calendar app? Or another one?

Can you attach an example - maybe there's a corner case.

I've got the same problem: If I try to edit an contact using the ics branch of 
kolab-droid, the contact app crashes.

Here is the stacktrace of it:
