Network-Manager shows sometimes incomplete panel menu

[Carsten Holzmüller]

The left-click menu of the network manager is sometimes incomplete. I need it for VPN and WLAN connection, but is shows only:
"Netzwerk aktivieren" (free translated: activate network)
"Funknetzwerk aktivieren" (free translated: activate WLAN)
"Informationen" (free translated: information)
"Bearbeiten" (free translated: options)

After log out and a new log in, the full menu is back (with all the WLAN and VPN menu entries).

I use Xubuntu an the xfce-Desktop.

I've also experienced this today using a fully updated 13.04
