Version:           4.6 (using KDE 4.6.3) 
OS:                Linux

Every time I try to reboot the computer, after disappearing all the windows, I always get a message about PolicyKit crash.

Reproducible: Always

Steps to Reproduce:
Just try to reboot or turn off the computer

Actual Results:  
I get a message about crash, Reporting Assistant offers to report a bug automatically, but says that there is not enough information and I should install additional debug symbols,  but it can't find those symbols so I have to report this bug manually.


Sorry for my English.

I got this Backtrace content:
