And to conclude this little saga (that nobody is probably reading, but at least
then there is a solution in the archives):
Adding the following to ~/.config/fontconfig/fonts.conf worked for me:
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<match>
<test name="family">
<string>Courier</string>
</test>
<edit mode="assign" name="file">
<string>/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf</string>
</edit>
</match>
</fontconfig>
Substitute your favorite (ttf/otf) monospaced font above.
Best,
Wolfgang
