The issue here is that the OP is using a local pip installation. This exposes a bug in the PyQt5 PyPI package, which
includes some invalid translation files. The problem can be seen if you install PyQt5 into a venv and then run lconvert
on the *local* qt_de.qm file, which produces this:


   <?xml version="1.0" encoding="utf-8"?>
   <!DOCTYPE TS>
   <TS version="2.1" language="de">
   <dependencies>
   <dependency catalog="qtbase_de"/>
   <dependency catalog="qtscript_de"/>
   <dependency catalog="qtmultimedia_de"/>
   <dependency catalog="qtxmlpatterns_de"/>
   </dependencies>
   </TS>

As you can see, this includes a dependency on the qtscript_de.qm file, which the PyQt5 PyPI package does not provide.
Unfortunately, QTranslator will refuse to load a qm file with missing dependencies, so the other files will be ignored,
and no translation will occur (i.e. load will return False).

PyQt5 has never provided the QtScript module, so the translation files should never include any dependencies on it
either. However, keeping the dependency and including all the qtscript_*.qm files would work just as well.

Phil: is there any chance this problem could be fixed?
