Comment:

 This is happening when a channel fails and at least one circuit that's
 pending for that channel doesn't have an associated guard state.  _That_
 can happen when we are trying to use a fallback directory, or when we're
 not using guards at all for some reason.

 The sensible fix here is in branch `bug21128`.  The underlying cause has
 something to do with a circuit that _isn't_ using a guard, not one that
 is.
