Sometimes, it is nearly as frustrating to use Debian than it is to use commercial software. For example, when one sees a simple bug completely unreacted on for more than one year. #405040 has passed its first anniversary since it was reported and touched for the last time. Visible reaction of the package maintainer: Nil.
It's a small thing, but an annoying one. And I still consider it unacceptable to let bugs rot for a year without the slightest trace of action.
