gnome acting strangely - a single symptom: indicator-applet crashed with SIGSEGV in g_cclosure_marshal_VOID__POINTER()

[Steve Embling]

Binary package hint: indicator-applet

Im fairly certain this is a symptom rather than a root cause.
Can in recovery mode login to gnome (unless going in via recovery Xorg segfaults), but metacity nor gnome-panels start. on starting gnome-panels, this occurs.
