Interpreting GV error popup

[Joe Pfeiffer]

I'm sure the answer to this question is RTFM, but so far I haven't
been able to find the right FM to R...

I'm generating a PDF file that appears to have a bug, since
ghostscript is choking on it.  When I try to open it with gv, I get an
error popup which appears to be trying to tell me what went wrong...

What exactly do the various stacks, errors, and functions described in
the error popup mean?

Like I said, please just point me at a manual...
