Yikes! If this is a simple grammar, you do some crazy parsing!

You have so much going on in this grammar, have you thought of using
something a little simpler, but just as self-descriptive, like JSON perhaps?
I know it uses delimiters instead of indentation, but pyparsing seems to be
really struggling with this input text.  You might also look at some of the
indented examples on the pyparsing wiki, and roll your own version of
indentedBlock, to see if you can make some better headway.
