Mayavi example crashes sphinx build - (think it's not tested by Travis) about sphinx-gallery HOT 3 CLOSED

Also, it seems that Travis is not testing the build of mayavi gallery examples (I might be wrong, but a quick search through Travis logs convinced me that it is not tested).

I can confirm this, we are not installing mayavi in the test environment and it is not getting tested.

I fixed the test issue on my branch https://github.com/Titan-C/sphinx-gallery/tree/mayavitest but I just noticed that as travis does not provide an X server, the build fails for mayavi. #56 Only avoid the pop-up of figure in build, but does not fix the need for the X server, like having the Agg matplotlib back end.

Regarding more into this issue. I tested in an anaconda venv with mayavi 4.4.0, and I have no problem running the mayavi example. But sphinx does gives me an error when parsing the examples, a problem more linked to the pygments and pyface packages that do the syntax highlighting.

You'll need the X virtual frame buffer:

Thank you. To get it to work in travis is a bit different, but now is done and the travis environment is tested. The mayavi example runs, but the build crashes as in my computer due to pygments and pyface.
