Version:           4.3.4 (using KDE 4.3.4)
Compiler:          gcc 4.4.2 
OS:                Linux
Installed from:    Compiled From Sources

Every time I start kde, I get the KDE crash Handler window pop up and inform that kded crashed with signal 6. I have both gentoo and lunar linux installed and I face this problem on both the distros !! It is reproducible in both the distros, every time I boot into KDE.

Here's the crash report from KDE Crash Handler:

I have recompiled Qt4, kdelibs and kdebase with debug enabled yet, there are some components without debug info as you can see from above report (libkdeinit4_kded4.so and solid_hal_power.so). I can't figure out which other packages I need to recompile with debug info. If you want me to fill in this information, please let me know which other packages I need to recompile with debug.

Please let me know if you need further information. Thanks.
