Marcel, i have found a little problem with your fix in tiffloader.cpp when 
image isn't in RGBA 8/16 bits. Your patch in this loader to use 
observer/progress info is uncomplete (:=)))

You can reproduce easily this problem using my images available at this url :

Trying to get thumbnails or to load in IE 07.TIFF, 12.TIFF, or 19.TIFF 
images...
