Whoops, chess-scene is not part of the convenience library, so that has nothing to do with this issue. Totally wrong about that, sorry.

Thank you Florian! I will move the upstream bug report to Vala. The signal declaration in Vala is: public signal PieceType? choose_promotion_type (); I guess Vala got confused by the nullability of the return value. It needs to use a different marshaller, or pass NULL to allow GLib to pick the best marshaller. https://bugzilla.gnome.org/show_bug.cgi?id=758816 Michael -- devel mailing list devel@lists.fedoraproject.org http://lists.fedoraproject.org/admin/lists/devel@lists.fedoraproject.org
