Do you have a matplotlibrc file that sets a Qt-based backend? The
default backend is TkAgg, which does not require Qt. (Note that PySide
is a Qt interface for Python.)

I myself have never created such a file.
I searched home with `find . -iname "*matplotlib*"`, didn't find the rc file
you mentioned except in some virtualenvs. But that should not be related.
By searching /etc as root, didn't find it either.

After some more checks, I can confirm your bug report. Matplotlib
actually does use Qt by default under Python 3. I still use Python 2
for most of my work, and under Python 2 matplotlib uses TkAgg as its
default backend.
After a quick look at the definition of python-matplotlib, I suspect
that python-pyqt should be a propagated-input, not a plain input.
I will try this out as soon as possible.
Konrad.

That was indeed the cause of the bug. I have submitted a patch:
