huh... ok the backupserver sent the first FIN... that's not what i
expected. i hope i didn't waste your time with the straces.
here's something i should have asked for at the very beginning: run
rdiff-backup with -v9 option (actually i think -v5 is good enough, but
it's been some time since i've done this). hopefully there'll be
something more illuminating in the output than the default traceback
gives.
