Failed to load any font ?

[cournape]

The following w/ enable 4.6.0 on a basic centos 6.5 system:

$ edm run -e build-env -- python -c "from kiva.fonttools import afm"

Even if there are no fonts installed on the system, we should fail more gracefully than this. In particular, if we can do it on use, rather than import, that would be better.

[corranwebster]

Also, this may be moot with #264, since that replaces all the fonttools stuff with a third-party package.

I tried enable master, and got exactly the same error FWIW.

FWIW, with enable 4.5.1 it prints the following lines and then proceeds normally, and creates a "kiva/fontList.cache" file in the preferences dir of my Canopy Data app. On the next launch, the lines aren't printed and the app launches normally. This is all using EDM on OS X. With enable 4.6.0 I get the error described in this issue.

Fontconfig error: Cannot load default config file

Adding the BUG label, since this seems to be a regression since the previous release of Enable.

This was fixed in master #272.
