when converting the attached PDF file into PDF (or TIFF) with GS HEAD (i tried 
older GS versions and got the same problem) the resulting PDF file contains 
blank pages. 
PS: Adobe Preflight sais that the original document is a valid PDF.

This is a /JBIG2Decode issue. The simplified sample file contains just
a single image.

The file is in fact invalid: the data length of the second segment inside the
JBIG2 stream is corrupt. jbig2dec consumes the entire stream without producing
output because it wants to buffer all the segment's data before starting decode.

If I replace the length with one determined from the size of the JBIG2Decode
stream, the file decodes properly.

A work around for this problem was committed as r8778.
