Version: (using KDE 3.5.8) Installed from: SuSE RPMs There is a similar report: https://bugs.kde.org/show_bug.cgi?id=39128 with bizarre resolution so I am opening this one. You can assign the same shortcut to two (or more maybe) applications. I would expect the same behaviour as kdelibs shortcuts settings -- checking for duplicates.
Duplicate checking has been implemented in kde core now.
