FC4 & Evolution 2.2.3 does not allow copy/move and copy/paste between calendars

[Thomas V. Fischer]

I am having a problem with the Calendar module in Evolution. If I copy/paste
an event, the application hangs and I need to either kill it or use
(evolution --force-shutdown).
The event does get copied but the application interface stops responding.

The same issue is reproducible if I try to move an event between calendars.

I tried this with a clean account and clean evolution settings as well. No
luck the same problems persist

Any ideas?
