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.

Did you rebuild kdebase-workspace with debug symbols ?
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 0x00007f356d35da70 in nanosleep () from /lib/libc.so.6 Thread 1 (Thread 0x7f3570aec700 (LWP 22403)): [KCrash Handler] #5 RandRDisplay::isValid (this=0x100000004) at /var/tmp/portage/kde-base/systemsettings-4.2.0/work/systemsettings-4.2.0/kcontrol/randr/randrdisplay.cpp:110 #6 0x00007f35669201d7 in LegacyRandRConfig::load (this=0x1307280) at /var/tmp/portage/kde-base/systemsettings-4.2.0/work/systemsettings-4.2.0/kcontrol/randr/legacyrandrconfig.cpp:67 #7 0x00007f356691e4b9 in KRandRModule::load (this=0x1162c40) at /var/tmp/portage/kde-base/systemsettings-4.2.0/work/systemsettings-4.2.0/kcontrol/randr/krandrmodule.cpp:106 #8 0x00007f356f99c5af in KCModule::qt_metacall () from /usr/lib64/libkdeui.so.5 #9 0x00007f356edb8326 in QObject::event () from /usr/lib64/qt4/libQtCore.so.4 #10 0x00007f356df79e6d in QWidget::event () from /usr/lib64/qt4/libQtGui.so.4 #11 0x00007f356df311ae in QApplicationPrivate::notify_helper () from /usr/lib64/qt4/libQtGui.so.4 #12 0x00007f356df372c2 in QApplication::notify () from /usr/lib64/qt4/libQtGui.so.4 #13 0x00007f356f90dac1 in KApplication::notify () from /usr/lib64/libkdeui.so.5 #14 0x00007f356eda8424 in QCoreApplication::notifyInternal () from /usr/lib64/qt4/libQtCore.so.4 #15 0x00007f356eda96b9 in QCoreApplicationPrivate::sendPostedEvents () from /usr/lib64/qt4/libQtCore.so.4 #16 0x00007f356edd1a23 in QEventDispatcherUNIX::processEvents () from /usr/lib64/qt4/libQtCore.so.4 #17 0x00007f356dfb152b in ??

Till than that's all I have.
