I'm definitely interested. The Arch maintainer filed an issue for the
same problem and attached his own patch here:
https://bugs.freedesktop.org/show_bug.cgi?id=107014

But as you said, the real solution has to be a port to Python3. Would it
be okay to drop Python2 support entirely? Doing so in a 1.5.x
maintenance release sounds too intrusive.

Should I target a 1.6.0 release with Python3 as dependency and also
include my "cxx-future" branch, where I require C++11?
