Control: severity -1 wishlist Control: retitle -1 Please add correct versioned dependencies
The bug originally presented on a machine that was running testing (and not unstable). I had used aptitude to pull a (presumably minimal) set of dependencies allowing kwin-x11 from unstable to be installed. That configuration---which naturally satisfied all stated dependencies---generated the bug. Using purely unstable does not cause this bug. I am reducing the severity to wishlist because, while it would be nice to have accurate dependency information, most users probably aren't going to experience this.
