Is this still valid with phonon-backend-gstramer 4.6.3 and a recent KDE 4.10.x? Then we need a debuglog, see also http://techbase.kde.org/Development/Tutorials/Debugging/Phonon Without feedback in the next 3 weeks this will be closed as invalid.

Is this reproducible with the current phonon-backend-gstreamer 4.7.2 or later? Please make sure to have the gstreamer 1.x libraries and plugins now.
This has been fixed in the meanwhile, Pipeline is now always initialized, so m_pipeline can never be null.
