plymouthd crashed with SIGSEGV in ply_trigger_add_handler()

I try to run 'GNOME session manager' and it did not show it's interface. Two crash messages was showned, this and another one called 'mission-control-5 crashed with SIGSEGV in g_slice_alloc()'. I decide to registre both here in launchpad but I'm not sure about its connection.
