Revenge of the nb_clean bug???

Does anybody else still have problems with Performer segfaulting on a
nb_clean() call down in its entrails? I just received patchSG0001414, which I
thought would cure my problems - no joy. Admittedly, I'm doing some squirrelly
things to the scene graph, but, darn it, it worked fine in 1.2! All I'm really
doing is splicing in some extra nodes into the scene graph of a vehicle model
loaded by the FLT loader. Is there a list of known combinations of actions that
trip the bug? I'll try to reduce it down to a simple case that crashes and post
it - in the meantime, here's the stack trace (if its any use...):
