There was a change in unittest autoloader in Python 3.5. It now tries to
import the package even if it has no tests. I do not know if it is an
intended change, or a side-effect of fixing some bug ([1]?). Maybe Robert
can enlighten us here.

This has caused some my packages to FTBFS too, for example see bugs
#800671 and #800139. So if it not an intended change, it should be fixed
upstream.

Python 3.4 is still the default version in Debian. We can't do the switch
at once, so the transition is split into three steps:

1) Add Python 3.5;
2) Make 3.5 the default;
3) Remove Python 3.4.

We are currently in the end of first step, AFAIK. And Python 3.4 will
be removed only when all three steps are finished.
