This sounds vaguely familiar, perhaps like:

net/msg00321.html
but I don't know if that had a resolution.  It doesn't seem common, though.

I don't think that's true.  Backuppc is going to insist on protocol 28 
which, I think, means it has to get the entire directory tree before 
starting the comparison.

Is your client rsync binary up to date with any distribution updates? 
Maybe it is just a bug that has already been fixed.  Also, I thought at 
one point you said this was only happening with incrementals.  Have you 
tried forcing a full run?
