Subject: [PATCH] Fix occasional start-up crash when reading GUI XMLs.
 _dialog_props holds SGSharedPtrs (pointers managed by reference counters).
 Explicitly casting the object to an unmanaged SGPropertyNode* and deleting it
 may cause heap corruption, since the following assignment "_dialog_props[..]
 = ..." also tries to delete the (already deleted) object.
