           Summary: KDE crash in dbus_connection_get_data: NULL connection
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: jharvell at dogpad.net


Application: polkit-kde-authentication-agent-1 (0.1)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-gentoo-r2-cujo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

Started KDE.  After a few seconds polkit-kde-authentication agent crashes with
a failed assertion as follows:

process 18053: arguments to dbus_connection_get_data() were incorrect,
assertion
 "connection != NULL" failed in file
/var/tmp/portage/sys-apps/dbus-1.4.0/work/d
bus-1.4.0/dbus/dbus-connection.c line 5980.
This is normally a bug in some application using the D-Bus library.
  D-Bus not built with -rdynamic so unable to print a backtrace
KCrash: Application 'polkit-kde-authentication-agent-1' crashing...
KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit
QDBusObjectPath: invalid path ""
QStringList
Solid::Backends::Hal::HalManager::findDeviceByDeviceInterface(Solid:
:DeviceInterface::Type)  error:  "org.freedesktop.DBus.Error.Disconnected"

The crash can be reproduced every time.
