Comment 1 Urs Wolfer 2009-12-19 18:02:27 UTC

Can you reproduce this crash?

Please install kde and krdc debug packages; the current backtrace does not include any useful information.

Comment 2 Mag. Ferri Leberl 2009-12-20 16:53:39 UTC

Grüezi ;)
Thank you for your feedback.
As to now I cannot reproduce the crash. Which packages should I install precisely? kdebase-dbg, kdebase-runtime-dbg and kdebase-workspace-dbg are installed; I didn't find anything like krdc-dbg in the repositories.
Looking forward for your hints and
Pfiat Gott,
Leberl

Comment 3 Urs Wolfer 2009-12-23 22:54:53 UTC

You should probably look for kdenetwork-dbg. If there are no such packages, please request them from your distribution.

Comment 4 Urs Wolfer 2009-12-24 23:25:15 UTC

Comment 5 Edward Hunt 2009-12-28 22:43:06 UTC

I installed kdenetwork-dbg and reran the crash report. It's available here:

I had this bug today while closing a session using ctrl+w. It didn't happen every time but I was able to reproduce it.

Comment 9 Urs Wolfer 2010-09-19 13:44:44 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 10 Børre Gaup 2010-09-20 09:13:33 UTC

Haven't used krdc in months, but I tested it today and couldn't replicate the crash.
I used krdc version 4.5.1 on Kubuntu 10.10

Comment 11 Urs Wolfer 2010-10-17 17:57:17 UTC

Closing as fixed since nobody can reproduce this crashes anymore with the fixes
from KRDC 4.5.
