Maya and incompatible bindings on PYTHONPATH

[mottosso]

Problem

Launching Maya < 2017 with a binding for Qt 5 on your PYTHONPATH may cause Maya to segfault due to picking up either PyQt5 or PySide2, when it only supports PyQt4 and PySide.

• Affects Maya 2016 and below.

Solution

Limit preferred bindings to those supported by your version of Maya.

# Linux
$ export QT_PREFERRED_BINDING=PySide:PyQt4
# Windows
$ set QT_PREFERRED_BINDING=PySide;PyQt4
$ maya
