[boost] [graph] 'short' in bundled property throws boost::bad_any_cast

Hi, I have a graph with a bundled property whose one of the members is a 'short'. When calling read_graphml, it throws an exception: terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_any_cast>

' what(): boost::bad_any_cast: failed conversion using boost::any_cast

Same problem with 'unsigned short'. With 'int' and 'long', it works.
