When Zeno commit a comment with https://github.com/zdavatz/spreadsheet/commit/9b08dceecf634139f819d1f9dcd0dbcdf10b4dbd on Wed Apr 2 19:00:32 2014 +0200
Our travis-ci build https://travis-ci.org/zdavatz/spreadsheet/builds/22119822 failed using ruby 2.2.0dev (2014-04-02 trunk 45502) [x86_64-linux].

The previous commit https://github.com/zdavatz/spreadsheet/commit/c901cd3f26191f33ff23301e757093d537425771 passed the travis-ci build https://travis-ci.org/zdavatz/spreadsheet/jobs/19648087 (about 2 months ago with ruby 2.2.0dev (2014-02-26 trunk 45182) [x86_64-linux])

The problem persists and is reproducible with ruby 2.2.0dev (2014-05-02 trunk 45788) [x86_64-linux],too.

We don't mind to adapt to Ruby 2.2 a few things, but I have no hint, which new feature broke the builds or whether it is really a bug.

Any hint would be very helpful for us.

Thanks in advance for your work!

Trying to narrow done the first occurrence I found that ruby 2.2.0dev (2014-03-29 trunk 45468) [x86_64-linux] https://travis-ci.org/ngiger/oddb2xml/jobs/21936566#L56 broke a different gem, too. Whhich leaves you still over 100 commits to look for. But may be you have a script for bisecting.
