Thanks for your answer, it indeed looks like a similar issue. 
Do i close this one as it doesn't looks like a bug but a stricter application of rules ?

See bug 1331797. This is a fault in the fonts being served by the Google site.

You can work around it by setting gfx.downloadable_fonts.otl_validation to false in about:config.
