$ pulseaudio
W: main.c: D-Bus name org.pulseaudio.Server already taken. Weird shit!
I thought a user facing error message like this is inappropriate, so politely took the issue upstream [1].Lennart, who I had spent some time with in real life a few months previous, didn't yet have the reputation for being the person he is today. I thought he'd be pretty reasonable about it. Instead he closed the bug as "won't fix" and left the comment, "Sorry, but please don't waste my time, will you?".
I was pretty shocked by his response, I lost a lot of respect for him at this moment and then wrote a long ass blog post about professionalism of developers and appropriate language for user facing error messages.. but still, Lennart tainted himself and showed the person we now know him as. (Also, if you are reading this Lennart, fuck you).
Ubuntu ended up carrying a patch simply to remove this inappropriate language, I never checked if it was eventually cleaned upstream or if other distros also removed it.
EDIT: I just checked, and it was eventually removed in 2011 [2]
