bug#38437: Cantarell Oblique fonts fail to render in some Gnome applications

Some Gnome applications (Claws Mail and Glade in my case) show
rectangles in place of characters. Screenshot of this is attached.
Terminal logs in these cases show for example:

(claws-mail:14616): Pango-WARNING **: 12:31:34.945: shaping failure,
expect ugly output. shape-engine='PangoFcShapeEngine', font='Cantarell
Oblique 11', text='Personal'

I've tried manually installing 'font-abattis-cantarell' into my
profile, which did not solve this problem.

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.

Regards,
Leo

Aha! I'd tried refreshing the user-level fontconfig cache with
'fc-cache -f', but I hadn't run that as root to refresh the system
cache. That did the trick. Thank you! :)

Hello.

Leo Prikler helped Jonathan Freder fix his issue by refreshing the 
system's fontconfig cache.

Going to go ahead and close.
