Example app crash

[riki-dexter]

Hi @jharwig,
your example app crashes when I touch 'Variable Width' tab with this error message:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[GLKViewController loadView] loaded the "7Iy-2i-DqV-view-KH5-vi-5Sl" nib but didn't get a GLKView.'
Thank you.
