Freeze the adapter to avoid invalid deref 

GTK tries to get the parent item of selected elements when unselecting.
If we don't freeze, we run the risk of crashing if a selected item is
removed before being unselected.  This causes a wx warning but a) this
is suppressed in release and b) warning message is better than crash.
See next commit for fix to avoid common case of the error
