[Mono-osx] 2.10.9 problem: How to avoid Fonts.conf calls?

Hi there,

I am bundling my application to make it work on machines without Mono

It worked previously but now, using Mono 2.10.8 or 2.10.9, mono framework
always tries to read the file:


I tried with a basic monomac application made with the wizard in which I add
the following call in MainWindow.cs Initialize function:

System.Drawing.Color c = System.Drawing.Color.Black;

If the fonts.conf file is not on the system, execution stops with the
console message:

Fontconfig error: Cannot load default config file

If I replace this call by:
System.Drawing.Color c = System.Drawing.Color.FromArg(0,0,0);

It works, but I have plenty of calls to predefined colors in my code, and I
don't understand this regression.

So, questions are: 
- why mono try to read this file when doing completely unrelated things?
- if this file is really needed, is there a way to put it on the application
bundle (ie: /Applications/MyApp/...) and tell mono to look to this bundled
fonts.conf instead of the one in /Library/Framework/...

Thanks for your help.
