I probably should have looked a little more carefully.
The topic crossbar.worker.worker-002.container.on_component_stop is assigned on line 760 of crossbar/controller/node.py as topic = 'crossbar.worker.{}.container.on_component_stop'.format(worker_id) . That of course is not a unicode string but of type str.
The assertion on line 1280 of autobahn/wamp/protocol.py is assert(topic is None or type(topic) == six.text_type).
Since topic is not None, the first assertion topic is None evaluates to False and the second assertion type(topic) == six.text_type is evaluated, which is False too. That causes the entire assertion to be False and the assertion exception to be thrown.
The question is what is wrong here. Should the topic be a unicode string and hence line 760 of crossbar/controller/node.py needs to be changed accordingly or should the topic not be a unicode string and therefore the assertion is incorrect?
Searching through the code shows that all other instances where topic are set and published unicode is used. Apparently this instance was missed. However, then of course the example code of hello.py also needs to be changed accordingly.
I got it working, I just don't know what the intended way is, otherwise I would submit the pull requests.

@rstreif You are running a new Crossbar.io against a app template created with a previous version?
Because I just tried to reproduce, and there is no such template in that version anymore:

Actually, I just tried the "hello/python/" example in this repo, and that did indeed fail now on Python 2 for me with the release 17.3.1, but I believe is fixed via the merging of crossbario/crossbar#1047

@oberstet Yes, crossbario/crossbar/pull/1047 is the exact fix that I did on my local copy of crossbar.

Ok, so I guess this can be closed. At least it is fixed now. Thanks for reporting back!
