title: Launching GIMP... Fontconfig warning: ignoring UTF-8: not a valid region tag
body: <p>I am running a python 3.5 application called Ortho4XP which, among other things, calls for Gimp at a certain stage; when it tries to launch Gimp I get the warning above and the script freeezes. My machine is osx El Capitan
  Searching stackoverflow I find similar questions and it is suggested to unchek "Select locale varoables on startup" but if I do this other problems appear and the script does not run at all.</p>
