Hi Christopher,

A lot of these warnings are the results of errors/incompatibilities in 
config files that fontconfig reads. The manual says "fontconfig is built 
with a large amount of internal debugging left enabled". :-) The config 
files can come from fontconfig itself or shipped by a font package. 
Uninstalling the fonts you don't need may make some of the warnings go 
away. In debian/ubuntu systems and may be in others too, the files in 
/etc/fonts/conf.d/ are just symbolic links to the real config files in 
/etc/fonts/conf.avail/, so you can try deleting the symbolic links and 
see the effect. Finally, you can edit the (xml) config files manually. 
See, for example,

User documentation here:

Hope this helps,
ST
