It's commit b7d8ecafc9d5a7a8e3d37128640061e1ad0eb9da which I think hasn't
been synced to INN yet (although I have used Git so much that I've
forgotten how to use Subversion, so maybe I'm missing it)... oh, yes, I
did miss it.  I think you already synced this as r10388, so I think the
Debian bug will be fixed by updating to code later than that.  (Obviously
a release is a great idea.)

Oh, yes, sorry Bo.  Will fix.  Thanks for the correction!
