Likely introduced by https://github.com/MariaDB/server/commit/0dbc66498d9222d91b73d4c0a8a40c96bd3dc296
And fixed by https://github.com/MariaDB/server/commit/b7ad1ba5d121d4fe4b0655e46076b6e50754b4e9

According to bb logs it seem to happen only on 2016-04-26, which supports my guess. And I tend to remember we discussed with Monty this failure on that day.
