Hi John,
sorry this has been a well-intended change in 2.1.2 that was added to protect
people from using a node with two different labels resulting in zero results.
Unfortunately it has many not so good side-effects. So we'll probably roll it
back in the next version.
Until then please use:
> START user = node(5)
> WHERE user:user
> RETURN user
