amarok does not work in latest factory release

amarok

(amarok:14160): GLib-GObject-WARNING **: cannot register existing type `GstObject’

(amarok:14160): GLib-CRITICAL **: g_once_init_leave: assertion `result != 0’ failed

(amarok:14160): GLib-GObject-CRITICAL **: g_type_register_static: assertion `parent_type > 0’ failed

(amarok:14160): GLib-CRITICAL **: g_once_init_leave: assertion `result != 0’ failed

(amarok:14160): GLib-GObject-CRITICAL **: g_object_newv: assertion `G_TYPE_IS_OBJECT (object_type)’ failed

Current solution would be to either switch to phonon-vlc-backend, or to compile a WIP phonon-gstreamer-1.0 (issue is due to QtWebkit compiled with gst 1.0 support)
