Back in kde 4.8 there was a combined toolbar button "open recent" wich opened the file open dialogue with a short click and opened the list of recently opened files with a long click. Apparently, this confused some users, so the behaviour changed according to bug #302358. I think this is a regression, so the optimal solution may be separate buttons for "open" and "open recent" as with current kde 4.10 plus an optional combined button with the old behaviour.
