Another bug caused by GObject floating references :') The GVariant returned by builder_end() is floating, and the way g_variant_builder_add_value works is that it _only_ takes a reference if floating. So basically if you have a RefPtr<GVariant> with a floating reference, then pass it to g_variant_builder_add_value, the reference is "stolen", but RefPtr doesn't know about it. It really sucks.
