Cancelling appointment works only partly

[T. Ribbrock]

Hi all,

I just ran into another little problem:

User A makes an appointment with user B. User B accepts and the
appointment is now present in both calendars.

User A then proceeds to delete that appointment and kontact correctly
offers to send out a mail to the participants.

User B receives the cancellation message, including a link to remove the
appointment from his calendar. He clicks this link - but the appointment
stays in his calendar.

Any hints as to how to debug this?

Versions:
- kolab 2.0.1 (fully patched) on SuSE 9.3
- kontact 1.1.2 (SuSE 10.0/KDE 3.4.2 Level "b")
- kmail 1.8.2 (SuSE 10.0/KDE 3.4.2 Level "b")
- korganizer 3.4.2 (SuSE 10.0/KDE 3.4.2 Level "b") 

Regards,

Thomas
