Comment:

 I'm guessing that this is happening before the step is run, so its
 properties haven't been rendered yet.  It's pretty tricky to determine
 whether {{{self.command}}} needs to be rendered (since the renderables may
 be buried in a list).

 This is relatively harmless, as you've seen - the waterfall renders,
 albiet with a traceback in the logfile.

 Still, I bet we can find a fix -- describe() should be resilient.
