we should check if everything works with 3.5 and maybe add it to travis?

Yes, that would be nice. Can you go ahead and check it? Thanks in advance,

I create a branch to test the support. As it could have been expected, there is not yet a PySide install for py35, so it fails there.

PySide can't be installed on python 3.5 yet. There is a fix in the pyside setup repository, but they didn't release a fix version through pypi yet
