[PATCH] Bug in genmarshal regarding return type OBJECT

[Johannes Stezenbach <js convergence de>]

(Repost in unidiff format, since I was notified that context
diffs tend to get ignored here...)

The marshaller code generated by glib-genmarshal
for return type OBJECT did not check for NULL return
values, which lead to warnings when calling the
type's release function (g_object_unref).
