how to debug/find error of kde crash?

[serengeti]

Hi
Kde is crashing somehow randomly on my openSuse 11.1 installation.
It happens when I am browsing with firefox, using dolphin, ark, gwenview ect. What I can observe is that without warning the screen becomes black and shortly after the kdm login screen appears. This is quite annoying because nothing of the previous session is restored and I loose work. There is no message telling that an error occured or similar.

Is there a possibility to find out what caused the crash (some log files or so)?

I am using kde 4.3.1

In the meanwhile I found an error message in /var/log/messages which might help to digg further into a direction:

kdm[2363]: X server for display :0 terminated unexpectedly

my guess was that a driver or similar causes X to crash.

checking the end of Xorg.log.0.old unveiled following:

Backtrace:
0: /usr/bin/Xorg(xf86SigHandler+0x79) [0x80cbc79]
1: [0xffffe400]
2: /usr/lib/xorg/modules/updates//drivers/nvidia_drv.so(_nv001647X+0x2b) [0xb66fc5fb]

Fatal server error:
Caught signal 11.  Server aborting

(II) UnloadModule: "kbd"
(II) UnloadModule: "mouse"

obviously! Nvidia again!!!

I do have the latest drivers, don't know what to do else...

The same here (for more then 2 months):

I think it is the compositing of nvidia that somehow fails.
If I turn it off, I don't get the crashs and not nice desktop effects...

Finally, I was able to make a copy of the .xsession-errors file (a restart overwrote it).
here it its content:

The program 'firefox' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 1152 error_code 3 request_code 20 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

There are quite a lot of error messages, but there seem to be two major ones: one involving firefox and one with nepomukserver. What is this nepomukserver doing anyway?

The program 'firefox' received an X Window System error.
