The bug is not fixed by replacing Gutsy's Ghostscript with the official 8.61 release. The bug simply only appears if Ghostscript is built as a dynamic library, as it is done in Gutsy. The users who solved the problem with the official release compiled Ghostscript statically (the default behavior when simply doing "./configure; make; sudo make install") and therefore the problem disappeared for them.

See

http://bugs.ghostscript.com/show_bug.cgi?id=689577

The bug occurs only if all of these conditions are fulfilled:

1. The input file is a Postscript file generated by Acrobat from an encrypted PDF file.
2. Ghostscript is built as a library (i.e. "make so", as Gutsy's Ghostscript).
3. The input file is sent to Ghostcript via "- <filename" or "cat filename | gs -" (printing system call Ghostscript this way).

Under these conditions it also occurs with the released Ghostscript 8.61.
