einfo will be NULL - thus the segv - it's probably because evas on the 770
either doesnt have the software_x11 engine compiled & installed or it's
installed weirdly/incorrectly and can't find the software_x11 engine as it is a
loadable module, not compiled-in :)

might be the same problem- loaders are loadable modules loaded at runtime -
can't be found - maybe dlopen() is not working properly in both cases?

this shouldn't be segving - it should silently fail- unless something deeper is
wrong - eg... dlopen... :(
