FWIW, I always read "file a bug report", when not used to mean "I need more detail" but to mean "talk to the hand" and when spoken by someone working close to a project, as "fuck off", particularly if the person never even bothered to determine whether or not you've used their bug tracker in the past (or even filed a bug already for this specific issue).
When I find someone on a forum with a bug that I haven't heard about, I sit around and talk to them until they either get tired of wanting to talk to me or I get the information I need to fix the problem. The alternative would essentially translate to "I don't actually care about this bug", as that's the only way you are going to get certain classes of bug report. I have shown people at Apple bugs that they were absolutely fascinated by momentarily and then told "File a Radar". I clearly wasn't in a position to do at the moment and which of course I forgot to do it when I got home... they should know this happens, because this assuredly happens to almost every single person they tell that to (and no, "well, we do see a large number of bugs filed" is not evidence against "people you tell to file a bug using your arcane system, particularly if they have to do it days later, probably won't"), and yet even when a potentially rare and real and critical bug is shown to them in person (this was even at an event where the whole point was to work with customers on their issues), their response is easentially "engh, I don't care if this doesn't work unless it affects a ton of people". As someone who works in security, I'm going to assert "do you want vulnerabilities? because this attitude is how you get vulnerabilities": every bug is precious as it is a mistake in your mental model of the software, and who knows how far down the rabbit hole that mistake will take you.
Sure: I realize that the engineer isn't always the best person to do this, and even in my tiny company I had to solve that, but the solution isn't to tell people to "go use the bug tracker", a comment which shunts annoying work learning a new system, one which is all too likely to demoralize them (Apple's Radar is a great example of this), but instead to have someone whose job is to talk to people to follow up with credible bugs: I'd go "hey Xyz, there's a guy on this forum who's complaining about something I hadn't heard of before; can you try to get more details from them?" (where Xyz has changed over the years, but has always been one of the few key positions). I couldn't begin to count the number of times I have debugged an issue with someone on reddit.
