alt-a is scared of nans #38

The attached image is a tif with floating point data containing a lot of nans. As I wanted to automatically adjust the contrast of this image with alt-a, I was surprised to get a full black image, even after cycling with more alt-a (the displayed range was consistently 3.4e+38..-3.4e+38). Shift-a handles them nicely though. Get the image at: https://www.dropbox.com/s/qlg4thnlpbejkl2/test_image.tif?dl=0
