Backtrace Bafflement
 

Hi,

Could someone please explain to me, just what my problem is? Is it limited to the gui for instance.

I've freshly installed Kubuntu 11.04 but It is very tempremental; The KDE Crash Handler can pop up at reboot with:

Executable: nepomukservicestub PID: 1580 Signal: Aborted (6)*

for instance, and frequentlely the screen freezes and the only (temporary) remedy is to reboot.

* I've hit the button inviting me to install Debug Symbols and the package is succesfully installed, apparently the "generated crash infomation ( a Backtrace) is usefull":
