### Please describe the problem.

`git annex test` show multiple failures on a samba mounted partition.

### What steps will reproduce the problem?

just run `git annex test` (in the mounted dir)

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

4.20130521, built for architecture `armhf` by the Raspbian maintainers ("jessie" suite at the time of writing)

### Please provide any additional information below.

Here are the last lines of `git annex test` output; AFAICT they are the only lines mentioning failures. Before them the output mentions `+++ OK, passed 100 tests.`.
