#31 gdkpixbuf new from file not thread safe

[Napuseno Smith]

I get this crash now and then. I cannot reproduce it at will. Apparently gdkpixbuf new from file is not thread safe (probably because XLib server/client is not thread safe since resources must be allocated on server). here's an example trace back from 4.8.0 release

Tentative fix in 4.8.0rc4, released today to the public.
