Yes, unfortunately boot1.efi has been broken on PRi3 for months.

A fix was committed in r325681 and will be in the next round of snapshots

jhb@ suggested checking the device for NULL as well, as in your patch,
and I'll make that change shortly.  In practice if the first call
works the second will as well, but your version is an improvement in
correctness.
