Tested: I took two shots, one rotated 90 degrees. My images happen to be
frames from a movie so, they don't have exif. If put in 40.5 degrees FOV
for the portrait image. and 65 degrees for the landscape image. Both
images show a focal length on the order of 29 mm. (correct!).

But one Image renders completely wrong.

To reproduce:

  http://prive.bitwizard.nl/test_pt.jpg

and enter the above FOV's for the images (40.5 for the pt and 65 for the other). 
Next click align. 

Tested on Pre-Release 2010.4.0.1e3fcb26cf9e

Bug description:
In gsoc2009_layout, the focal length shown on the camera and lens tab does not match up with the focal length from trunk. This occurs when the image is a portrait fisheye image. The focal length is out by the aspect ratio.
