Use VPN connections in network-manager-pptp without rebooting

When configuring VPN connections in Ubuntu through network-manager-pptp the connections don’t get displayed until a reboot due to a bug. In the bugtracker I found a solution which makes the connections available without a reboot.

First, restart dbus

sudo /etc/init.d/dbus restart

Then run the NetworkManager applet by opening a command window with ALT+F2 and typing nm-applet.
