I read glyphobet's blog, itemizing frustrations he's had reporting bugs to Ubuntu. While I've not had frustrating experiences reporting bugs to Ubuntu, I've reported bugs to a lot of different open source projects, and had more than a few closed in a way I wasn't happy with, so I can definitely sympathize. I hope in Ubuntu these sorts of experiences are the exception, but certainly there's always room to improve.

In my own experience at having bugs closed in ways I thought were inappropriate or incorrect, while I was initially angry about it, after reflecting I realized in each case it was really a consequence that I didn't understand that particular project's bug philosophy and had filed the bug in a way that didn't adhere to their guidelines.

In working on X.org for Ubuntu, I've handled a LOT of bug reports, and while I personally try to be very cognizant of handling the reports in a respectful way, I've seen a lot of basic mistakes that reporters make, that will likely make it hard to get the solution they're hoping for.
