I cannot reproduce this issue in a clean Utopic amd64 chroot. Can it happen that you have a custom build of Qt installed?

[Romeo Disca (romdisc)]

Can you specify "custom build of Qt".

I have installed the current sdk from Qt developing some C++ apps.

Does this collide?

[Dmitry Shachnev (mitya57)]

You should use the packaged PyQt only with packaged versions of Qt.

[Romeo Disca (romdisc)]

I compiled and installed pyqt5 from the sources with qt5.4.1.

Now it works.
