16 bit grayscale PSD bug

Hello,

    There is a problem during conversion of 16 bit grayscale PSD files. It seems IM
cannot understand them, or is getting confused. Converting to JPG, the result looks like static.

[gouda:root]/home/alex# convert 16bit_grayscale.psd 16bit_grayscale.jpg

You can download the test image and the result here:

P.S.- GraphicsMagick has the same problem. I reported it there too. Thanks.
