I don't understand what is going on, please help! Libtiff has had many such bugs in the past. They have to do with errors in the TIFF directory reading code (libtiff bug). This same bug bit me before. It is related to the big-endian CPU rather than 64-bit compilation. The easiest solution is to upgrade your libtiff to a version without the bug.
