One more thing to clarify - when you said it was fixed in .3 and .4 did you mean 7.3 or 7.2.3?
Thanks!

Could you give me some idea on what circumstances cause this to happen?
IIRC, it's an order-of-operations mistake during backend shutdown: the proc structure is deallocated while it's still possible to receive an interrupt from another backend --- and if you get such an interrupt, you need the proc. So from the user's point of view it's pretty unpredictable.
Short answer: upgrade. This is not the only nasty bug in 7.2.1.
