It doesn't crash with LIBGL_DRI3_DISABLE=1.

I've tried Mesa master (76f687d5a5be9d3bce8d05bcfef97a3d74ca1f18) and
xf86-video-intel master (f5469681b620d9d6ccaf53e92ed31f931cb03b0d), but
it's the same.

The crash happens since mt is 0, but other members looks strange (Width,
Height, ...).

I don't know why, but doesn't crash any more now.
It could be any update to the given packages, so I don't know if the root cause is fixed, or if some change just avoids the problem.
