           Summary: KDE can't shutdown, restart the computer
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: cacouret at wanadoo.fr


Application: polkit-kde-authentication-agent-1 (0.1)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35.4-28.fc14.x86_64 x86_64
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
- What I was doing when the application crashed:
If I demanded to KDE : restart, shutdown or disconnect the user, I have this
bug. But I don't have problem with TTY or Konsole for that.

- Unusual behavior I noticed:
KDE closed software (but not all), I couldn't see Plasma and the screen freezed
(but the cursor is active and the keyboard, but not the rest of screen). 

I must killed X or went to TTY, and with KDM or a command, I could shutdown the
computer.

I use Fedora 14 Alpha with KDE-Red Hat repos (stable, testing and unstable)

The crash can be reproduced every time.

-- Backtrace:
