+Subject: [PATCH] engine: Don't crash when emitting PropertiesChanged for NULL
+ values
+
+When emitting PropertiesChanged, avoid putting NULL values into the
+changed_properties array (and then subsequently crashing for the NULL).
+Instead, use the invalidate_properties array that only lists the changed
+property names, avoiding issues with NULL GVariants.
