Comment(by jsalvatier):

 The attached file has a very small modification to _cubicmin() which
 solves the particular problem I was experiencing. It looks like _quadmin
 right below _cubicmin could also use the same check. Perhaps there's a
 better way to do the check though. I also don't know what other places
 need similar checks.
