Interesting. I wonder if this is a Python3 or newer-PyQt4 thing. Do you know what version of PyQt4 you're using? We might have to workaround this, but should be doable. Interestingly, it seems to be okay here (debian/sid). I've included a short python transcript below showing how to get it.

$ python
Python 2.7.10 (default, Jun  1 2015, 16:21:46) 
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt4.QtCore import PYQT_VERSION_STR
>>> PYQT_VERSION_STR
'4.11.4'

Oh, sorry, forgot to mention my software versions. I am using python3, so that might be the problem.
OS: Arch Linux
