You have a partially out of date or multiple installs of gnuradio:

This is the master branch:
http://gnuradio.org/cgit/gnuradio.git/tree/gnuradio-core/src/python/gnuradio/gr/top_block.py#n129

This is the next branch:
http://gnuradio.org/cgit/gnuradio.git/tree/gnuradio-core/src/python/gnuradio/gr/top_block.py?h=next#n129
