gnome-pilot installs a Other > PilotSync menuitem. There are a couple of problems with this: 1. It shouldn't be in Other 2. "PilotSync" is pretty bad for a menuitem 3. It doesn't even work
4. Looks like it tries to launch a panel applet! Yeah, I noticed that too. There's a "Pilot Applet" item in the "Add to Panel" dialog, so I'll just remove the broken desktop file.
Fixed in gnome-pilot-2.0.16-2.fc9.
