Another update,

The mailing list post still hasn't been approved. I messaged on GIMPnet
about it not too long ago so hopefully the appropriate people will get
pinged eventually. The team is currently busy with GUADEC so it's
understandable they may be running behind on moderating posts on a not
too traffic heavy mailing list[1] :)

In terms of the patch, I've inserted the necessary code into all the
accompanying files and Nautilus builds successfully. During my testing I
threw a return statement in there and confirmed it blocked all file open
attempts silently, which is intended behavior.

I've stuck the WIP code up on Github, currently it segfaults but the
cause is known. I'll be modifying the qvm_trust.py NautilusPython
extension to make use of this method soon, and once it all works out
I'll provide some pre-made .RPMs for testing.

Thanks
Andrew Morgan
