Sentry Crash Report:

Description Monty Scroggins 2009-02-27 19:21:02 UTC 
Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    SuSE RPMs

I am running openSUSE 11.1 with KDE 4.2. I have been remotely connecting to my host successfully via nomachine's 'nxclient'.  The update (via yast2) on Monday or Tuesday causes KDE 4.2 to fail to open when attempting to use nxclient to connect.   I can successfully connect to the host and run other window managers, only KDE 4.2 is currently failing (and this only recently began happening) 

The error being reported is this - 

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

Comment 1 Monty Scroggins 2009-02-27 19:22:57 UTC 
In case this helps as well.. the error dialog displays this - The application Plasma Workspace (plasma) crashed and caused the signal 11 (SIGSEGV).
Comment 2 Dario Andres 2009-03-02 01:13:21 UTC 
We still need some other information.
If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? 
You need #to install the "kdebase4-workspace-debuginfo" and "kdelibs5-debuginfo" packages
Thanks :)
Comment 3 Monty Scroggins 2009-03-02 04:24:07 UTC 
Anything I can do to help!  I love KDE and want to do my part..  Let me know if there is anything else you need.  I am happy to oblige.

I created this crash on a different machine than the original one.  

The machine config is - 

OS:  Linux 2.6.27.19-3.2-pae i686
System:  openSUSE 11.1 (i586)
KDE:  4.2.00 (KDE 4.2.0) "release 102"
Video:   GeForce 9300 GE/PCI/SSE2
Video Driver:   3.0.0 NVIDIA 180.29
Processor (CPU):   Intel(R) Core(TM)2 Quad CPU Q6700 @ 2.66GHz
Speed:  1,600.00 MHz
Cores:  4
Total memory (RAM):  3.9 GB
Free memory:  2.1 GB (+ 1.1 GB Caches)
Free swap:  2.0 GB

I have the latest nx packages installed - 
nxclient-3.2.0-14.i386.rpm  nxnode-3.2.0-11.i386.rpm  nxserver-3.2.0-13.i386.rpm


All I have to do to recreate the problem is fire up nxclient and try to login to a host with kde selected as the desktop (my kde is 4.2 with all the latest updates).  It doesnt seem to matter whether kde is already running on the machine.

Here is the crash report - 

Application: Plasma Workspace (plasma), signal SIGSEGV
