Why didn't you check? From what I can tell when I did, there is no color profile in the original image so it'll default to sRGB. This really looks like a gamma issue of some sort (see @perching_aix's comment).
Make sure to send me the images that crashed it (support at flyingmeat.com)! I'd love to get that fixed, as I'm not aware of any cases right now where this happens.
