GtkFileFilter / GtkRecentFilter not using exact mime detection.

[Stefan Kost <ensonic hora-obscura de>]

hi,

I am using GtkFileFilter / GtkRecentFilter in my app with mime-type filters. 
Unfortunately the filters use only the quick way (looking at extensions). Can 
the somehow be configured to do exact sniffing?
