Description transpose 2011-09-18 19:42:40 UTC
Application: krdc (4.6.2 (4.6.2))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
Crashes quite randomly. I have the impression that it crashes more frequently when using CTRL keys, though.
Using kdrc from ubuntu 11.04 repository, the remote desktop is Xvnc coming with ubuntu 10.04/gnome.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KRDC (krdc), signal: Segmentation fault
