This is not tesseract but leptonica issue (library used for image handling).
When I run it on linux I got error message comming from leptonica (1.67 -> I
did not try 1.68 on linux yet):
Error in pixReadFromTiffStream: spp not in set {1,3,4}
Error in pixReadStreamTiff: pix not read
Error in pixReadTiff: pix not read
On Windows leptonica "release version" library did not show error/warning
messages because of compile option "NO_CONSOLE_IO" (see
http://code.google.com/p/leptonica/issues/detail?id=42).
It looks like leptonica did not support lzw compression for tiff ( see
http://www.leptonica.com/source/README.html "9. Image I/O" - lzw is
mentioned in png and gif section, but not with tif). I change
tif compression from lzw to zip (BTW: this will cause smaller image),
tesseract will produce ouput (on XP SP3).
