Bug 285020

Application: krdc (4.6.00 (4.6.0) "release 6")
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.7-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

KRDC crashes randomly, but not very often. I use it on a locat net with an OSX server (the client performance is set at 'medium quality' for performace reasons). The crash seems to be related to keyboard/mouse events, though I haven't figured out a method to voluntarily trigger the crash.

The crash can be reproduced some of the time.

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