Version: (using KDE 4.3.0) Installed from: Ubuntu Packages clicking on [undo=rückgängig] in the menu returns a popup which says "nothing can be undone". I would suggest that if there is nothing to be undone the this point should be greyed out so that the user can not click on it instead of the popup
SVN commit 1011825 by mkoller: BUG: 203197 fix usage of the undo action to use the correct name M +4 -4 kmmainwidget.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1011825
