I am not sure to agree. The unexpected (by you :-)) behaviour at hand
is about Emacs and "M-x shell"; and I will not speak "in general".

I cannot even open "evince" inside Emacs shell...

My point is: it is more complicated than only the environment variable GTK_PATH.
Well, if you feel it is a bug, please open a bug report detailing what
is the problem. Personally, I do miss what it is and what could be
