> How often do you actually receive quality bug reports at work?

Very, very often. I work as a QA engineer whose main responsibilities is to go through the bugfixing queue and add needed info where necessary. And I have to spend a lot of time every day doing this. Sometimes it gets so bad I have to assign the ticket back to the reporter to add more info, because even I don't know where to look without it.

Interestingly enough, it's always the more senior people at our company who are guilty of writing crap bug reports.
