I think I managed to get this to happen once inside gdb: clicking ardour's 'Close' button brought up the 'save session' dialog, but once I'd dismissed that (I can't remember which button, but it was probably 'just quit), ardour was unresponsive. I hit <Ctrl>+C in gdb, and got a backtrace (ardour-scroll-freeze-bt): don't know if it's of any use... |
