These files were produced by an old, or at least an incorrect,
version of the DVI->PS utility.  The PostScript code tests whether it
is running on a printer, or at any rate an interpreter with job
encapsulation (i.e., non-zero initial `save' level), and even though
it attempts to handle the situation where this is not the case, the
code for handling the alternative case is wrong.

You can work around this problem by feeding Ghostscript a file with
the following contents before feeding it any of the files mentioned
above:
	save pop
