If this is a patch against the stable version, and there is no
objection from the list, I'm happy to push it to testing.
(it may not happen before this weekend because I'm spending the whole

> Well, a stable release with a nasty little bug is just that: a stable release with a nasty little bug. I needed it to be fixed.

Definitely!
