Description ete 2009-02-17 19:02:56 UTC

Version:            (using KDE 4.2.0)
Compiler:          GCC 4.1.2 
OS:                Linux
Installed from:    Gentoo Packages

As soon "Anzeige" is klickt on systemsettings crashes and signal 11 SIGSEGV apears. 

I tried to get better backtrace, but even with Gentoo's debug option turned on and fomit-frame-pointer removed I still don't get debugging symbols 
sorry



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 Dario Andres 2009-02-17 23:36:11 UTC

Did you rebuild kdebase-workspace with debug symbols ?

Comment 2 ete 2009-02-18 19:33:07 UTC

Ok. I figured it out. Gentoo strips the symbols even if I use the "debug" option if not told otherwise. So I rebuild systemsettings and got this

Application: System Settings (systemsettings), signal SIGSEGV

I will rebuild the whole KDE with debug symbols, but thats going to take a couple of hours. Till than that's all I have.
