+Subject: [PATCH] GtkBuilder: Ensure types are fully initialized
+
+Just calling get_type() does not ensure that the signals, properties
+and everything else gets set up properly. Ensure it is, by calling
+g_type_class_ref() before using the type. This fixes the testcase
+added in the previous commit.
