Yes, it also fails running the example in the help page for ReadImage:

     -->RGB = ReadImage(IPD_PATH + 'demos\teaset.png');
      !--error 4
     Undefined variable: Dimensions
     at line      72 of function ReadImage called by :
     RGB = ReadImage(IPD_PATH + 'demos\teaset.png');

     -->

     -->figure(); ShowColorImage(RGB, 'Result');
                            !--error 4
     Undefined variable: RGB


There is something wrong with ReadImageFile.
Running ReadImageFile example from the help page fails:
      - Dimensions is undefined
      - PixelList contains the filename of the image to open:
         -->PixelList == IPD_PATH + 'demos\teaset.png'
              ans  =

               T

So, yes, there problem is not related to that particular image.
