At first, I thought people would respect the issue template. In practice, very few do, even when a proper bug is reported. I completely agree with you but it seems to be a losing battle. So I just deal with these kinds of cases according to my mood. Concerning the bug #967, maybe I was not angry enough. Overall, the atmosphere on the bug tracker is fortunately very positive.
I think having one set of fairly clear and complete polite responses to the question to then be linked from elsewhere (or possibly turned into an FAQ ... and then linked to when people inevitably don't spot it in the FAQ before opening an issue ;) is probably a net win in terms of maintaining a positive atmosphere on your bug tracker.
