Corrupt stacks

Since corrupt stack are so rare, I was surprised to apparently run into
one on my last project.
I'd been working on the stack for a couple of months when suddenly one of
my cards wouldn't print. When I'd issue "print card" (either via script
of message box) on that card, I'd get a hard freeze (on a Mac). Force
Quit wouldn't work. I'd always have to reboot. Printing any other card
worked fine.
I'd been using Chipp's autoArchive plugin to save versions as I went
along. I went back through about 10 versions, each time going to that
card and printing. Eventually I found the version that caused the crash.
Every version from that one had the bad card. Everything else about the
stack (as far as I could tell) worked fine. I compared all the code
between the last good stack and the bad one and there wasn't any
difference. I tried printing on two different printers with the same
results.
This stack was never subject to a partial save. I didn't crash during a
save and never ended up with a ~ file.
The strange thing is, when I sent this stack to RunRev, they couldn't
reproduce the crash when printing. So, was this stack corrupt? It seemed
to be, but I don't know why the print crash couldn't be reproduced on a
different system.
In any case, that's the only potentially corrupt stack I've run into with
Rev.
