Damn, damn, damn.  Nope.  Here's the deal: even on red hat 7.2,
only the first couple of errors invoke gdb properly.  After
that, when gdb is invoked, something is wrong with stdin;
gdb thinks it's at EOF.  Think openoffice is closing stdin?

For what it's worth, here's the bug I'm really going after:
http://www.openoffice.org/project/www/issues/show_bug.cgi?id=14046
To reproduce it, just load the file FR0453p.doc into ooo1.1beta1 or
the later snapshot build 644_m11.
Without valgrind, you have to click on the first page, click Format/arrange/send to back
(or any of the other arrange commands, probably), then undo,
to trigger the crash.  With Valgrind, I get

as soon as the file finishes loading; you don't even have to do the
send-to-back/undo thing.  Saying 'y' to valgrind at that point
starts gdb, but it goes haywire as if the keyboard isn't really
attached anymore.  I'd like to get a backtrace with gdb there.
