Ardour Segmentation fault- won't start at all!

Is your disk full?  "df -h" should tell you.

You may also want to remove the .deb that is cached in
/var/cache/apt/archive before you reinstall.

Is there anything in /var/log/syslog that shows up at the same time
you try to run ardour?

You wouldn't happen to be over-clocking this computer would you?
