https://bugs.kde.org/show_bug.cgi?id=273315

           Summary: kopete blocks indefinitely when using "now playing"
                    plugin
           Product: kopete
           Version: 1.0.80
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kopete-bugs at kde.org
        ReportedBy: rezbit.hex at gmail.com

Application: kopete (1.0.80)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.37-hardened-r7 i686
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:Using kde 4.6.2, amarok 2.4.0
If a music player (I tested with kscd and amarok) freezes, kopete blocks
indefinitely on dbus, until the given processes is killed.
This can be simulated by sending SIGSTOP to a music player.

- Custom settings of the application:
DIsabling "now playing" prevents this problem.

The crash can be reproduced every time.

-- Backtrace:
Application: Kopete (kopete), signal: Segmentation fault
