Comment 1 Urs Wolfer 2010-09-19 13:55:27 UTC 
We have fixed some crashes in the VNC plugin recently. Can you still reproduce this issue with a recent version of KRDC (from KDE SC 4.5 or later)?
Comment 2 Marc Chamberlin 2010-09-19 21:56:40 UTC 
With KDE 4.5.1, SuSE 11.2 I am unable to reproduce this crash. That said, there are other issues using KRDC. I cannot connect to or use the KRFB server. When connecting to an x11vnc server it is sluggish and has poor update characteristics. Using KRDC to connect to a RealVNC server on a WIndoz machine worked fine. But these are probably separate issues...
Comment 3 Urs Wolfer 2010-10-17 17:44:13 UTC 
Closing as fixed since nobody can reproduce this crashes anymore with the fixes from KRDC 4.5.
