authorization window appears below other windows

Binary package hint: kpackagekit

When installing or removing software, the authorization window that prompts for your password appears below all other windows and has no focus. You have to minimize all windows or select the window from the taskbar to make it appear. It should appear above the main window of kpackagekit with focus.
