Please describe the problem.

This is a weird one. I'm getting rsync protocol version mismatch -- is your shell clean? on a particular file.

I have tried to reproduce it but not been able.

  • First time it happened, I went to the problem repo and did a get, which worked, destroying the evidence. "Luckily", this happened again a few days later.
  • I thought maybe it was because there was a partial transfer in .git/annex/tmp with some specific characteristics. Nope, if I remove the file in tmp the problem remains.
  • I made another clone think it was the problem repo, transferred the file to that repo, no problem. Dropped it, pointed everything back to the original bad repo. Still bad.
  • Both sides are running rsync version 3.1.0 protocol version 31.

What steps will reproduce the problem?

Working on it. But I want to put the preliminaries here, in case someone else has seen this.

What version of git-annex are you using? On what operating system?

Both sides are running git-annex version: 5.20150508-g883d57f, on Ubuntu 14.04.2 LTS.

Please provide any additional information below.
