thumbnailing problems - exif orientation

["Dr. Michael J. Chudobiak" <mjc avtechpulse com>]

Users are starting to notice ugly thumbnailing problems because Nautilus 
ignores the exif orientation tag in jpeg files, whereas modern viewers 
like gThumb and eog respect the orientation tag - but they also share 
thumbnails with Nautilus.

Which means that thumbnails are sometimes right, sometimes wrong, 
depending which application generated them. To the user, it seems random.

So... can I gently prod the Nautilus crew into fixing this? libexif has 
"issues", I agree, so maybe a mini-parser can be written to just read 
the exif orientation tag.
