Doc Text:
Attempting to process a PDF file generated by Xerox WorkCentre resulted in an empty output. This was caused by the fact that in these documents, the segment data length field of the last segment is set to "-1", which was not handled correctly. With this update, PDF files generated by Xerox WorkCentre are now rendered as expected.

Proposed patch from upstream svn commit 8778

This is from upstream commit 8778:

       * [r8778] jbig2dec/jbig2_page.c: Work around broken JBIG2Decode
         streams created by several versions of
         Xerox WorkCentre. Bugs 689841 and 689852.
        
         In these streams, a segment data length field is written as -1
         expecting the decoder to infer it from the length of the
         remaining
         data.
