Test fails with numpy version 1.9.1

Created by: siebenkopf

When compiling against numpy version 1.9.1, one of the tests fail, regardless of the python version: bob.learn.em.test.test_plda_trainer.test_plda_EM_vs_Python; see: https://travis-ci.org/bioidiap/bob.learn.em/jobs/63327282. However, with the latest numpy version, the test passes again, see: https://travis-ci.org/bioidiap/bob.learn.em/jobs/63453315

Also, with older numpy versions the test seems to pass. So, maybe it is just an issue with this numpy version, and not with bob.learn.em. It would be nice to investigate that further.
