"free multibody" should do the trick.

A number of potential multibody problems are addressed by the breve 1.8
beta (http://www.spiderland.org/breve/breve_beta_1.8).  Although I 
haven't
come across this bug specifically, it is possible that it's what you're
describing is a different manifestation of one of the bugs that was 
fixed.
[ note: some physics bugs have been reported in the beta version which 
cause
incorrect results, but should not cause any crashes. ]

If you haven't done so already, you should try to repeat this with the 
new
beta.  If you're still having problems, please email me the simulation
code that triggers the error and I'll have a look at it.

You should not have to.  Once again, let me know if the problem 
persists in
the new beta.
