Tests fail on TravisCI

See here for example, and the many failures before it. I've managed to reproduce the problem using the following Dockerfile:

I didn't do a very good job following our git workflow this time... Nor last time now that I think of it. I rewrote the history (if you cloned this in the last few days, sorry!) to put master and stable back into their pre-1.1.2 state, and I'm now doing this properly on the release-1.1.2 branch.

So I can see in the output that the doctest tests pass and that it's the "Test suite reference" part which fails, but if I comment out the doctests and leave only the test suite reference, it passes. There an interaction between my tests?

[gelisam]

I remember that doctest tests can interact with each other because ghci's state is kept between tests, and I've had to reorder some of the tests over the years to avoid mysterious deadlocks. I don't understand how doctest could have an impact on non-doctest tests.

Great, now TravisCI refuses to run our tests, I guess we have to upgrade the format of our .travis.yml file or something.

ERROR: An error occured while trying to parse your .travis.yml file.

Please make sure that the file is valid YAML.

http://lint.travis-ci.org can check your .travis.yml.

The log message was: Build config file had a parse error: "did not find expected key while parsing a     block mapping at line 9 column 1".

"Fixed" in #173 by disabling the tests. I'll re-enable them in #174.
