qarte No module named 'PyQt5.QtSvg'

[G.M.]

Just upgraded qarte. It doesn't start anymore.

Bad deps have been set for the package!!!

Traceback (most recent call last):
  File "/usr/bin/qarte", line 116, in <module>
    from core import Core

    from PyQt5.QtSvg import QSvgRenderer
ImportError: No module named 'PyQt5.QtSvg'

Installing lacking package:
apt-get install python3-pyqt5.qtsvg

Results in another error:
