No, it's nil. Sorry, I was forgetting that not everyone
has the same keys! This isn't part of the bug, just a
way to make the behaviour more visible.

It is "invisible", but I would have expected the item not to
appear in the agenda at all rather than leaving a gap.

Whether scheduled items should be hidden is an interesting
question: if I'm meant to do something at a given time, it
would be helpful to know that something is stopping me. That
applies even more to deadlines.

P.S. Matt - I have org-enforce-todo-dependencies "t", which
is another possible difference that might stop this happening
in your case.
