[Image-SIG] Loading Big-Endian Floating Point TIFF Files

Hello Python Image folks,
I'm using PIL 1.1.7.
I would like to load a TIFF file that stores its pixels in 32-bit
big-endian floating point format. When I use Image.open it reads the file
and mode is given as "F;32BF", however if I use the convert or getdata
methods I get:
/usr/lib/python2.7/dist-packages/PIL/ImageFile.pyc in load_prepare(self)
229 if not self.im or\
230 self.im.mode != self.mode or self.im.size != self.size:
--> 231 self.im = Image.core.new(self.mode, self.size)
232 # create palette (optional)
233 if self.mode == "P":
ValueError: unrecognized mode
However, if I say
image_tiff = Image.open(file_tiff)
if image_tiff.mode == "F;32BF":
image_tiff.mode = "F"
image = numpy.asarray(image_tiff)
It will .convert() properly. It seems that there is a bug in the TIFF
loader that is mistaking the raw mode for the mode.
