I noticed that in the menu Settings > Configure Shortcuts, for many items there are 2 identical lines, only one of which actually assigns a shortcut.

All those actions have double entries, but only one of the entries actually controls the short cut. Changing the other one, respectively, doesn't do anything.
I'm using Kplayer 0.6.1 and Kubuntu Edgy with KDE 3.5.6.
