Version: svn (using KDE 4.2.2) OS: Linux Installed from: Unlisted Binary Package Easy to reproduce - fill a playlist (in my case i let dynamic playlist fill it with random songs) and minimize amarok while playing. After a few minutes restore it - it looks like in the attachment. Clicking inside of amarok makes the playlist reappear.
