text in idraw gives /rangecheck errors in recent versions of ghostscript

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.

Is it possible this is a ghostscript bug?  Or is it that idraw always
generated bad postscript, but that ghostview just got more
conservative lately?
