This is due to the way the various attribute wrappers are set up. 
Pango::Attribute is a real boxed wrapper for a real boxed type.  The others,
like Pango::AttrSize, are then set up by hand to inherit from Pango::Attribute
and thus from Glib::Boxed.  If one of these attributes now goes out of scope,
Glib::Boxed::DESTROY is called.  But since Pango::AttrSize is not registered
with the boxed type wrapper machinery, no C-level destroy function is called.

I attach a patch for Glib which makes this issue go away, but I think this
approach is very incorrect under certain circumstances.  See the patch for
details.

muppet, what do you think?
