Description of problem:
I've had trouble with old idraw files giving the following error
message in recent versions of ghostscript on Redhat Linux.

I haven't been able to find any related bug reports in the ghostscript
bug list.

Specificially, the attached idraw file (created with idraw 1.0.6 with the
text string "bar" in it), the gv the file using ghostscript-6.52-9.4 on
Redhat 7.3, it gives the following error message:

Position 10438 is the first character of the "End" just after
the "] Text" line in the file.

(FYI, idraw's native file format is postscript with idraw-specific comments.

This problem didn't happen on Redhat Linux 7.2, but it persists even
if I downgrade ghostview in RH 7.3 to the 7.2 version
(ghostscript-6.51-12).  (Suggesting perhaps it's a library problem,
rather than a problem directly in ghostscript.)  The problem persists
in rehdat 8.0 beta with ghostscript-7.05-20.  (I haven't been able to
test gs-7.30.)

The idraw folks seemt to think this is a ghostscript bug since the
idraw files that used to work no longer do.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. download 
<http://www.isi.edu/~johnh/PUBLIC/idraw_failing_in_ghostscript_020808.idraw>
(the extension is .idraw but it's really a postscript file)

2. try and ghostview it (run "gv
idraw_failing_in_ghostscript_020808.idraw")

Under RH 7.2 this succeeded, under RH 7.3 it fails with the error

Expected Results:  It should render an image of a black square and the text "bar"
in the ghostscript window.


Additional info:

The problem's been reported both to
the 
idraw (ivtools-users.net)
and 
ghostscript (bug-ghostscript)
maintainers,
but it's not clear if it's an idraw problem (bad postscript only now caught)
a ghostscript problem (a too strict or buggy interpreter)
or some sort of interaction with libraries (suggested
by the fact that downgrading to the RH 7.2 ghostscript doesn't fix the
problem).
