I was suspecting something like this too. But the question is that the CRS of the input image should be, by definition, unknown. In case the input image has a CRS, this CRS should be just ignored. Instead, the plugin actually prompts the user about the CRS of the input image. And I do not find any way to set the input CRS to unknown or just arbitrary x,y coordinates (while this is possible in Grass).
Where you say: "Upon resetting the CRS specified in the layer properties to the correct one, all was well" do you refer to the input or to the output image? Agus 2011/11/27 Dennis M.
