As i wrote in bug#470564 "I got the same bug and can confirm that removing the frei0r-plugins solves this issue.
But removing gstreamer0.10-plugins-bad solves it too, as described in bug#471690 , without having to remove the frei0r-plugins ( Openshot depends on it ). So it seems that these two plugin packages ( frei0r-plugins and gstreamer0.10-plugins-bad ) can not co-exist without causing trouble." It must be either frei0r-plugins or gstreamer0.10-plugins-bad who is causing this bug. -- Launching totem when frei0r-plugins is installed shows: Could not load classifier cascade https://bugs.launchpad.net/bugs/459940 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to rhythmbox in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
