ghostscript 5.10-1 chokes on A4

[Robert King <king@solzhenitsyn.ens.gu.edu.au>]

Following an upgrade from hamm to slink, gv (and ghostview) complain about
opening my postscript files with the following error message.

=========Error message from gv==============

Error: PostScript interpreter failed in main window.
==============end error message from gv==================

Downgrading gs to  3.33-7 fixed this problem.  The postscript file
that produced this error message is available at
http://www.ens.gu.edu.au/robertk/example1.ps

Any ideas on why?

Thanks,
Robert.
