Ive largely stopped reporting bugs to Ubuntu because of the condescending and dismissive attitude from their developers.
That doesn't sound in line with the spirit of Ubuntu:
A bizarre bug that was ignored for two months, only to have Timo Aaltonen declare, incorrectly, that the problem was in my fstab without ever asking to look at that file. The bug was closed without resolution, even though I replied stating that the Aaltonens explanation was incorrect. The bug silently vanished when I upgraded to Ubuntu 7.10.
