Looks like your problem is with whatever carries the rdiff-backup
stream.  rdiff-backup doesn't know anything about MACs, so probably
ssh is giving you that error message.  Once the connection fails,
rdiff-backup goes down, complaining about the remote connection.

Why does this only happen with one directory then?  I don't know,
maybe rdiff-backup needs to send more data across than with the other
directories, or something like that.
