fontconfig-2.5 claims "No fonts found"

[Per Osbeck]

When right clicking on a flash movie (flashplugin-nonfree-9.0.115.0ubuntu2) the flash area dies and turns grey.
Looking at the console output from Firefox:

No fonts found; this probably means that the fontconfig
library is not correctly configured. You may need to
edit the fonts.conf configuration file. More information
about fontconfig can be found in the fontconfig(3) manual
page and on http://fontconfig.org

This is when using fontconfig-2.5.0-2ubuntu1 (hardy).

Downgrading to gutsy fontconfig-2.4* shows a nice meny when right clicking.

Oh, this is on amd64 btw.

My 32bit seem to be working.

fontconfig-2.5 also messes up the fonts in my Bibble Lite 4.9.8 (http://www.bibblelabs.com).
All characters looks like squares.

Again, downgrading to 2.4 works.

Seems to be fixed with fontconfig-2.5-2ubuntu2
