The attached file will reproduce the error.  It has two elements: the
string "bar" and a box. The box will display in gv, but the string
crashes it.  Deleting the sring makes the problem go away.

However, you won't see this problem under RH 6.2.  It only starts
breaking in RH 7.3 (it works fine in RH versions through 7.2).

I agree it's likely that it's really ghostscript that's changed.

But it's not clear if idraw was always generating bad postscript and
only now does ghostscript complain, or if ghostscript is complaining
unfairly.
