Maybe someone wants to come up a fix for:

http://git.gnome.org/browse/gitadmin-bin/tree/validate-doap
http://git.gnome.org/browse/gitadmin-bin/tree/semi_rdf.py

To fix this? semi-rdf.py is designed as a non-validating parser, so it
is supposed to parse correct RDF and has unspecified behavior on
incorrect RDF. But if this is a recurring problem, then we should make
it catch this.

(With a quick look, startElementNS in the elseL of self.__depth % 2 == 0
needs to check if self.__object is non-NULL and raise an exception.)
