The ghostscript people in http://bugs.ghostscript.com/show_bug.cgi?id=691339 told me to use the -P- switch, and marked it "RESOLVED WONTFIX". I guess -P- should be the default, as well as -dSAFER should be. The way gv invokes gs is "wrong". For example, using command gv /tmp/any.ps will do: chdir("/tmp/") execve(..., "gs", ... "-dSAFER", ... "any.ps", ...) So gv is careful to use -dSAFER but does not know about -P-. I notified bug-gv@xxxxxxx about this, see http://bugs.debian.org/583316 also.
