Have you tried refreshing your fontconfig cache (i.e. the system cache
in /var/cache/fontconfig)?  I encountered similar issues a while ago
with System Monitor and Tweaks (and so did others, who also reported
the bug), and it seemed to be caused by a stale cache.  IIRC you don't
need to install Cantarell as user, but you may still do so if you wish.
