What operating system and CPU are you using?  Under Intel/FreeBSD the
image reads fine, but warns: "unknown field with tag 34665 (0x8769)
encountered. (TIFFReadDirectory) [No such file or directory].". Under
SPARC/Solaris the program crashes, apparently in the jpeg library
code.  Maybe there is a data allignment problem.

Warnings from libtiff are normal due to vendor-specific tags.  If you
don't care about them, you should ignore the error.  For Magick++,
this consists of adding a try/catch block around the read() call which
catches Magick::Warning exceptions and ignores them.
