Non-placeable geoms always returned the ode.environment dummy Body (this 
is a PyODE Body class without an underlying ODE dBody. That's why it 
crashed when you actually tried to access the ODE body).

I've changed this so that there is no dummy Body anymore. 
ode.environment still exists, but it simply holds None. Calling 
getBody() on a Space will now return None instead of an empty Body. 
Creating an empty Body class is not possible anymore, now you must pass 
a World object.
I've also modified the attach() method of the joints as was suggested a 
while ago. It's now ok to pass None as one of the arguments.

Agreed and done. :)

It's all in cvs...
