Comment 6 for bug 1495826

This error seems to be in the /prnt/filters/hpps file. The file handle output_fd is never opened. The line opens the file (150) is commented out. The issue is that when the HPPS filter throws an error, it attempts to write to a non-existant temp file. It could be solved by uncommenting line 150, or even better, adding some exception handling. See attached patch.
