Running the command "xfce4-popup-places" does nothing at all. I expect it to pop up the "Places" menu applet. (Just to confirm which applet this is: right-click panel, panel preferences, items tab, applet is called "Panel (external)".) The other xfce4-popup-* commands pop up okay (applicationsmenu, windowmenu, directorymenu). Furthermore, xfce4-popup-places writes nothing to the console no matter what arguments I pass it. All the other xfce4-popup-* commands display something when given "--help" as an argument.
Fixed in http://git.xfce.org/panel-plugins/xfce4-places-plugin/commit/?id=89bad7fa73fcd9c61a67735c00f0eb3bb9c864af
