Okay here is more helpful backtrace captured at the moment I get a
property update for the volume key which is not of the expected gdouble
type but instead NULL.
Breakpoint 1, volume_widget_property_update (item=0x98c26a8,
property=0x990fdb0 "x-canonical-ido-volume-level", value=0x0,
userdata=0x9a003a0)
at volume-widget.c:137
137 g_debug ("where are you coming from");
