Finding a bug and reporting to the developers should be encouraged.
I noticed that my co-worker's left brake light was not working when we left work. The next day I made sure to tell him so he wouldn't get a ticket. You're saying I should have bought the replacement bulb, brought in my tools, and fixed it on my lunch break?
I don't know about your analogy. It might be more like, hey your turn signal is out, it probably needs a new bulb. I'm not saying you have to provide a fix. But, you will find that things get fixed a lot faster if you do. Basically, it is not enough to complain about something, you should try to provide a solution.
