NetworkManager crashed with SIGSEGV in g_type_check_instance_cast()

[Sense Egbert Hofstede]

Binary package hint: network-manager

After a while or right from the start NetworkManager is just gone. The icon is there, but its left mousebutton context menu says: "No NetworkManager". The computer, however, is connect to the network.
