Is it possible that now the icon is removed or partially unref'ed and then CD_APPLET_STOP is called? well, the dock destroys the icons that belongs to a dock when this one is destroyed. so it's possible that the icons created by the applet are already destroyed before actually, it's quite possible since this applet is a plug-in (= has no icon, so no link to a dock). a solution is to register to the destroy notification on the icons created by the applet, and when the callback is called, remove it from its internal list of icons.
