OpenSUSE :: Adding Submenu With Correct Icon To KDE 4.4.4 Panel In 11.3?

I'm a KDE3 user who just upgraded to 11.3/KDE4 and is still trying to learn the new way of doing things, so please bear with me if I've overlooked something obvious. I've managed to mostly get my desktop the way I want it, except for one problem: I want to add a submenu to the panel, with an appropriate icon.

According to Bug 189583 - Ability to add submenu "like editors" to kicker panel from classic menu this capability was added over a year ago, so I should be able to just right-click on any submenu and the option to add the submenu to the panel or desktop should pop up. Except for me, it doesn't. Right-clicking on a submenu just selects the first item in the submenu instead of bringing up the context menu. I've tried both the classic and kickoff menus, and the same thing happens.

The bug report does mention it is also possible to add a submenu to the panel from Dolphin by going to applications:/ and dragging the folder to the panel. This does add the submenu, but the icon displayed on the panel is the question mark icon, and there seems to be no way to change it. Besides being ugly, I need different icons to tell different submenus apart.
