Could you post the messages related to the crash that appear in the
output of dmesg? (not that it would be useful, if the nvidia binary
driver is linked into the kernel nobody will even try to make sense of
the problem).

I think there are instructions here:

  http://ardour.org/debugging_ardour

Right after ardour crashes, is there anything in the output of dmesg or
in /var/log/messages that seems relevant?

This is very strange... which version of ardour are you running?
