The reason of the bug was that the shortcut was defined in both kde's "Configure Shortcuts" and "Custom Input Settings" systems, so it was invoked twice.
Rename the bug to not allow the conflicting shortcuts between "Configure Shortcuts" and "Custom Input Settings".
Setting the same key combination in both systems should result either in error or in a warning
