It's a bug in the recent refactoring that's been done to ec2test.
Without a test suite, things like this are bound to happen. Michael's
branch at lp:~mwhudson/launchpad/ami-from-scratch fixes this.

Alternatively, look it lib/devscripts/ec2test/builtins.py, find
cmd_demo, look for the 'run' method, and change the final line and add
the 'instance' parameter after 'runner'.

I don't know why the traceback is so lame.
