Phil,

thanks for that super fast reply. Of course I did not read that (although on the top \
of the document). Sorry. So I understand that this is a runtime issue. I typed

# export DYLD_FRAMEWORK_PATH=~/Qt5.5.0/5.5/clang_64/lib/
# python3.4
> > > from PyQt5.QtGui import QImageReader
> > > print(QImageReader.supportedImageFormats())

and now I have "svg" and "svgz" among the results and the SVG QIcon are rendered as \
expected.

Thanks a lot for that quick help (and also for that wonderful software),
Marko
