Update-notifier fails to run. Multiple fontconfig warnings

Noticed that I was not getting automatic updates. So killed the process and ran it from terminal.
$ update-notifier

I then ran sudo fc-cache -f -v which is why I reduced the errors to just the /etc/fonts/conf.d/90-fonts-nanum.conf errors.

As a workaround renaming/etc/fonts/conf.d/90-fonts-nanum.conf to backup enables update-notifier to run.

Also the /etc/xdg/autostart/update-notifier.desktop file seems corrupted. It got attached to this report via ubuntu-bug.
