Thank you for the reply!
I discovered that PyKDL no longer uses sip in their upstream, they switched to
pybind11, but that version is not released yet. So once a new version is released
and packaged for Debian, this problem will be resolved. Until then, I am
importing PyKDL before PyQt5.QtCore, as you recommended.
