If I open a vncserver session, e.g. 'vncserver :1" there will be a window appearing saying that the kde daemon crashed. I tried using the automated bug reporting system but it said that it could find appropriate debug packages for the task. At the same time, the buttons of the mouse do not work, the pointer is a double horizontal (or 45 degrees) arrow. I disabled desktop effects but it didn't make any difference. If from a konsole I enter 'metacity --replace' then the mouse button works. This problem occurs exactly the same in two different machines after upgrading to kubuntu 13.04, problem that didn't occur in its past version.

Reproducible: Always

Steps to Reproduce:
1. open a vncserver application
2.
3.
Actual Results:  
a window appears notifying that the kde daemon crashed.

Expected Results:  
just open the session on instance :1 (or other)
