I'll see if I can look at it some more later, I'm in the middle of something else right now. All I can say at the moment is that I've encountered problems like this in my own code many times, and it's always been a matter of having to carefully keep track of how the nested iterators coming out of groupby are being consumed. I doubt there is a library bug. Using groupby for things like this is powerful, but unfortunately bug-prone because of how these mutable iterators work. I suggest making some sample sequences and stepping through with a debugger seeing just how the iterators advance. -- http://mail.python.org/mailman/listinfo/python-list
