I get an assertion failure "width <= bytes_per_row" from this file in 
tiff_unpack_strip(), before the lzma code even comes to play.
libtiff seems to be able to handle it, though, so could open a ticket in track 
after this gets committed (Without this patch the decoder just aborts as soon 
as it finds it's lzma).
