           Summary: PolicyKit crashes every time I reboot the computer
           Product: kde
           Version: 4.6
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: artkun at guitarplayer.ru


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:
