Sample image t14.exr has wrong display window?

I was finally adding support for the display window to my application 
and using the reference images as examples.  I found I could duplicate 
all that is expected except for image t14.exr. According to the README 
that file should show only one pixel. However, when I read it with my 
application, I get:

                 x    y      x2    y2   w h              x y    x2 y2   
w    h
displayWindow=(-100,-100 - -100,-100) [0-0] dataWindow=(0,0 - 399,299) 
[399-299]

and thus no pixel or image at all.

Also t01.exr says it should have the same display window as the data 
window.  However, the display window for that image is:

displayWindow=(0,0 - 0,0) [0-0] dataWindow=(0,0 - 399,299) [399-299]
