Here's exactly what I see when trying to start it in 11.10 after enabling the Magnatune plugin:
$ rhythmbox /usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases ** ERROR:/build/buildd/pygobject-3.0.0/gi/_gobject/pygobject.c:929:pygobject_new_full: assertion failed: (tp != NULL) Aborted -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to rhythmbox in Ubuntu. https://bugs.launchpad.net/bugs/820191 Title: rhythmbox crashes on start if ubuntuoone music store plugin is installed (SIGSEGV in g_typelib_get_dir_entry_by_gtype()) Status in “rhythmbox” package in Ubuntu: New Bug description: Did try to start the ubuntuone music store on oneiric using the nightly ppa of ubuntuone. Problem: If I try to start rhythmbox no window opens. Instead the program crashes a few seconds later. The messages I get until then are: `menu_proxy_module_load': rhythmbox: undefined symbol: menu_proxy_module_load (rhythmbox:8449): Gtk-WARNING **: Failed to load type module: (null)
