If its just an X freeze and not a system freeze, and ulimit -c was set, 
and another machine is available on your network (I assume alot, im 
spoiled i guess) you can ssh/telnet in and kill -s 11 <pid of ardour> to 
force a segfault. I take these measures since I never have good luck 
getting very far with ardour running inside gdb.
