[Python-modules-team] Bug#844620: [python3-qtconsole] missing dependency on python3-pyqt5.qtsvg or alternatives

[Arian Sanusi]

Package: python3-qtconsole
Version: 4.2.1-2
Severity: normal

--- Please enter the report below this line. ---
python3-qtconsole has a missing dependency on PyQt5.qtsvg or alternatives. Most possibly stumbled when starting jupyter-qtconsole. Understanding this got harder because upstream messed with python's import...

>>> import qtconsole.qt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/qtconsole/qt.py", line 23, in <module>
    QtCore, QtGui, QtSvg, QT_API = load_qt(api_opts)
  File "/usr/lib/python3/dist-packages/qtconsole/qt_loaders.py", line 309, in load_qt
    api_options))
ImportError:
    Could not load requested Qt binding. Please ensure that
    PyQt4 >= 4.7, PyQt5 or PySide >= 1.0.3 is available,
    and only one is imported per session.

    Currently-imported Qt library:   None
    PyQt4 installed:                 False
    PyQt5 installed:                 False
    PySide >= 1.0.3 installed:       False
    Tried to load:                   ['pyqt5', 'pyside', 'pyqt']

this is _not_ resolved by just installing python3-pyqt5, but rather by installing python3-pyqt5.qtsvg - the dependency should alternatively point to the appropriate PyQt4 and PySide, but I did not investigate which package should be the dependancy exactly.
