It sounds like the new libtiff is not entirely compatible with the old libtiff. It may still work if JPEG compression is not used. Try

   convert file.jpg -compress none file.tiff

and see if that works.

Indeed, that does work! What does it imply? =)

It implies that the JPEG compression support in your new libtiff is not working correctly. However if you can create JPEG-compressed TIFFs using libtiff's own tiffcp then the implication could be that ImageMagick is somehow at fault, or that the binary interfacing between ImageMagick and libtiff is not correct.
