Luminance HDR crashes when trying to align a set of images (Hugin's align_image_stack). I know that some can't be aligned (completely black), but that's something that happens a lot when making HDR probes.

It seems to be a problem when Hugins' alignment tool we use.
Assuming you are using windows, download
and replace the installed align_image_stack.exe from Luminance with the newer version. At least in the dev-build of Luminance the alignment succeeded. Anyway, there should be a new release soon
