[Campbell Barton]

We're aware of this problem, I raised this exact issues a while back
on this list with the subject:
 "Exposing Tool Settings - issue with 2.5x"

That is how when you unwrap a model and then load in an image the UVs immediately distort to match the aspect ratio of that image; causing you to have to unwrap again. Often times this is not really a problem since unwrapping again isn't a big deal and most the time the images mapped will be square. However, in the case of an imported model that does not have seams and that was not unwrapped with Blender's default "Unwrap" command there's no good way to fix this except to modify your image to make it square, or to just scale the UVs as best you can. Honestly I can't think of a single reason why this behavior would be wanted…
