I found a workaround.  Instead of using the default python interpreter,
I can run mnemosyne using ipython:

% ipython /usr/local/bin/mnemosyne




I would like to ask, if someone could install mnemosyne and the
problem described above.  If so, I could fill up a PR.




Please add my email to the CC field in reply.



Thank you in advance and best regards
