Bug Description
First, some info on my installation:

I see that Bazaar is using an older version of Python on my system. Not sure what to think about that.
So there are a couple of commands that will actually result in a very similar error, but I put "help hidden-commands" in the Summary line of this bug because that's the command whose traceback I posted below.
Here it is:

So the immediate cause here is the plugin_info plugin you have installed in ~/.bazaar/plugins is broken, the .py file has a syntax error due to a "<<<<<<<" conflict marker.
So removing or fixing that plugin, or running with --no-plugins, would fix this for you.
bzr itself should cope better when a lazy-registered command from a plugin fails to load for whatever reason though, so this is also a valid bug in bzr.
