you are right, another look at the source was needed, but your analysis was off

Problem was my declaration of my end_foo() functions:

there are no attributes of end tags, doh.  Removing the extra option made
everything happy.

The error message is because the end_ function I defined had two parameters and
the one it was expecting only took self.
