Seeing this on two systems that went through F13-F14 upgrade.
version: gnome-applets-2.32.0-1.fc14.x86_64
symptom: via right click on a gnome panel, perform "add to panel" and choose the command line Mini Commander. Nothing appears on the panel. Do it a COUPLE of times if you want. Nothing happens.
symptom 2: from a shell, execute
/usr/libexec/mini_commander_applet
At this point, all of the mini-commanders you added suddenly pop into view on the panel.
Anyone else seeing this, and better yet, have a solution?
