Just run into a tif image which crashes XnView v1.80.3. It's surely a corrupted image: the second half of the file is missing. I'm not sure, maybe has some other corrupt data, but Windows Picture and Fax Viewer has no problem showing it up.
Download original image here (2.8MB):

I've created a 150KB version, which is just enough to crash XnView:

(I suspect XnView would crash on the full image as well, cause there are no glitches 'at 150KB' on the original picture.)
Anyway, XnView rocks!
