Bug#909728: fontconfig: Spams console with message Unable to revert mtime: /usr/local/share/fonts

[Matijs van Zuijlen]

Package: fontconfig
Version: 2.13.1-1
Severity: normal

Dear maintainer,

Fontconfig has started spamming the console with messages about not
being able to revert mtime:

    Unable to revert mtime: /usr/local/share/fonts

For example, this happens when I start gvim from one of my gnome
terminal windows.

I believe the message originates from the following line in fontconfig's
source code:

https://github.com/behdad/fontconfig/blob/d1f48f11d5dffa1d954a1b0abe44ce9e4bfc3709/src/fccache.c#L140

Kind Regards,
Matijs
