Crop image dialog box sometimes
shows 0 for cropped image width (pixels)
If you crop a non-panoramic image immediately after using Perspective
cropping on a panoramic image, the Crop image dialog box shows 0 for the
cropped image width (pixels). Although the dialog box displays the wrong
value, the result image is still correctly cropped.
None is needed -- the image is properly cropped in this situation.
Corrected in V4.2.
