We have fixed a few issues which could lead to such a bad situation
in the KDE Kolab Client, which is Kontact from the Proko2 branch.
Check the release notes of 2.1.5.
There is one potential corner case left:
kolab/issue1473 (conflict after moving day appointment)
Deadlock should not happen with 2.1.5 anymore.

The Proko2 branch is the conservative choice for production systems.
We are forwardporting all fixes to KDE 3.5 
and are interested in bug reports for this as well,
so it is reasonable to use, but of course we do have less control
there and what the distributions package. 

Best,
Bernhard
