I remember a test where some students were asked to prove something, but it was actually incorrect. However, constructing a counterexample (or even spotting that it was incorrect) was not trivial at all.
One or two students did manage to come up with a counterexample, and they were rewarded points for the problem. I think that's only fair.
But note, I'm not talking about typo's or trivialities here. I just think that spotting errors and being able to explain why it is an error might be worth some points...
There's a difference between rewarding someone for spotting a mistake (which I agree with so far as a few marks go) and then allowing others to continue without flagging the mistake (of course, unless as per your example the question demanded it).
