Quick notes:
* The changes are made directly to the source tree, rather then as
patches applied at package build time. Ideally we want the latter, but
its probably trivial to fix - a job for the weekend (they just need to
go in debian/patches, and get added to the series file if needed).

I noticed this, could you file a bug upstream if its a valid fix?
