I think that just display the an eventually warning is not enough. We
 have to leave segfault.

If this Warning happens, it implies the gtk engine couldn't start and
the app wouldn't run anyway (or could try and segfault). Also, you
could just call exit after your print that message, it was just a
correct template on how to proceed when importing gtk fails.

By this way we have to check if the waring is
 associated to display too.

Why ? Just checking for DISPLAY, like you proposed, doesn't solve this.

 Att, João Medeiros.
