When built with gstreamer USE flag, qtwebkit:4 will load gstreamer-0.10 in memory. But when amarok starts playing, it uses phonon-gstreamer expecting gstreamer-1.x, resulting in a crash. Maybe the root cause is that the gstreamer should be renamed gstreamer0 in qt-webkit:4? Or is there a way that both versions of gsgreamer could be loaded without crashing? Reproducible: Always Steps to Reproduce: 1. Install amarok with specified versions of dependency 2. Start amarok and hit the play button Actual Results: Crash Expected Results: Play Please see the kde bug report, https://bugs.kde.org/show_bug.cgi?id=358804 as they redirected me here. Also, in order to workaround the crash: one can add dev-qt/qt-webkit:4 -gstreamer in /etc/portage/package.use, or use another phonon backend.
Unfortunately there's been little traction on resolving this for quite some time. *** This bug has been marked as a duplicate of bug 522880 ***
