I am just rendering a pdf to tif which has an JBIG2 encoded image inside. The resulting image is just blank without any error message coming from ghostscript. The same behavior I found with ghostview trying to show the pdf using version 8.6 of ghostscript. Even with debug flag set there is no error message to inform me what is going wrong. Acrobat reader can show this pdf without problems.
