Google Wave Python Tutorial - Nothing happens

For the Google Wave Python Robot Tutorial, my capabilities.xml is vi开发者_运维百科sible and I can add it to a Wave, but the robot isn't actually responding to the events. I checked the logs, but I've fixed it so I'm not getting any more errors. Any suggestions?

There's known issue with Wave API: Issue 158 Fix is ready and is expected to be deployed in "coming days".
