I agree using serf instead of neon makes the error message go away. But it also doesn't actually show the list of files affected by the commit like it should. See "svn diff --summarize -r2967" for all the files that should be shown there.

Also, even when I change http-library to serf in the servers config file, svnsync still shows the "Observed changes didn't match count" error. Does svnsync not use this library setting?

I suppose we should report the problem to Google Code and hope they can uncorrupt the repository somehow? Apparently a couple dozen subsequent revisions see the same error, through r2993.
