It took me nearly 30 minutes to find out how to reproduce this issue 100 % reliable: - a confirm dialog must be shown (thanks a lot to Dario for the hint!) - the most important part: the keys (e. g. Shift + Del) must be pressed long enough until the confirm dialog grabs the focus from the details view... BUG: 220898 BUG: 183386 BUG: 203112 svn path=/trunk/KDE/kdebase/apps/; revision=1073043
