>Description:
Ghostscript 8.71 crashes with messages '/undefined ... copy_trailer_attrs' when invoked from gv, also from other programs such as Firefox. This is when viewing PDF files.

There is a documented error in one of the .ps files, which causes this. The file in question is lib/pdf2dsc.ps.

Patch shown below.
>How-To-Repeat:
Use gv to view a PDF file.
>Fix:
Patch below.
