           Summary: polkit-kde-agent-1 crash after two dialogues were
                    opened
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: arvidjaar at mail.ru


Application: polkit-kde-authentication-agent-1 (0.97.1)
KDE Platform Version: 4.5.80 (4.6 Beta1)
Qt Version: 4.7.1
Operating System: Linux 2.6.36.1-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2011.0"

-- Information about the crash:
- What I was doing when the application crashed:
polkit-kde-agent-1 GIT 99d1369a.

I started program that requested authentication;  I missed agent window because
it does not get focus automatically and so started another instance of program
that also requested authentication. This time I tried to enter password but
polkit-agent was unresponsive and ignored OK completely. When I closed both
agent instances one of them crashed (I believe, the last one closed).

-- Backtrace:
Application: PolicyKit1-KDE (polkit-kde-authentication-agent-1), signal:
Segmentation fault
