[kontact] Event not removed in automatic

[Alessio Cecchi]

I have made this test:

enviroment:
-kolab rc4
-suse 9.2 + kde 3.3 + kontact proko2 rc3
-2 users A and B

User A make an event, and invites user B (an email is sent from A to B).
B receives an email from A for the meeting and accept.

The event automatically is added to the calendar of B.

User A delete the event, an email is sent to B, from A, in order to ask 
  if B wants to cancel the event:

---
...
The meeting has been canceled
Remove this from my calendar
...
---

B click on "Remove this from my calendar" but the event is NOT deleted 
from his calendar.

Is this a bug?
Thanks
