    Bug 743034 - file-tiff-load crashes if I try to open a BigTIFF file
    
    Use a Babl format that actually exists for extra channels. Makes the
    plug-in load black pages from the mentioned "Rome" BigTIFF, so this
    only fixes the plug-in crash but doesn't fix loading of BigTIFF
    images, whatever they are...
