+Bug 699654: Check the restore operand type
+
+The primary function that implements restore correctly checked its parameter,
+but a function that does some preliminary work for the restore (gstate and
+device handling) did not check.
+
+So, even though the restore correctly errored out, it left things partially done
+and, in particular, the device in partially restored state. Meaning the
+LockSafetyParams was not correctly set.
