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

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.

The tiffcp tool has the same error.

I have tried compiling and installing other versions of libtiff, both more recent and older than the version installed by the auto updater. (I tried versions 3.7.1 and 3.8.2) But the problem persist. Could anyone tell me what file it is that is causing the rror? Which one should I look for to be updated? Not all of my libtiff libraries seem to update when I do the make install. Listing my libtiff library files look like this:

2006-05-16 08:56 libtiff.a
2006-05-16 08:56 libtiff.la
2006-05-16 08:56 libtiff.so -> libtiff.so.3.7.1
2006-05-16 08:57 libtiff.so.3 -> libtiff.so.3.8.2
2006-05-16 08:56 libtiff.so.3.7.1
2006-05-16 08:44 libtiff.so.3.8.2
2006-05-04 10:39 libtiff.so.4 -> libtiff.so.4.1.3
2006-05-03 13:44 libtiff.so.4.1.3
2006-05-16 08:44 libtiffxx.a
2006-05-16 08:44 libtiffxx.la
2006-05-16 08:44 libtiffxx.so -> libtiffxx.so.3.8.2
2006-05-04 10:39 libtiffxx.so.0 -> libtiffxx.so.0.0.3
2006-05-03 13:44 libtiffxx.so.0.0.3
2006-05-16 08:44 libtiffxx.so.3 -> libtiffxx.so.3.8.2
2006-05-16 08:44 libtiffxx.so.3.8.2

Thanks for the help so far,
