Try and construct a test case that crashes without user interaction.  i.e.
something that starts up with a known image, supplying a script to load via
Fuel.  Once this crashes reliably debugging is easy.  Otherwise its very
hard.  As soon as you have the crashing test case let me know and I'll take
a look.  Ideally it would run on Mac OS  X.

best, Eliot
