since a few days I'm seeing a weird behaviour of the NetworkManager-applet in Gnome.
The "Edit Connections" line is greyed out, so I'm not able to call the nm-connection-editor. From the command line everything works as expected.
Additionally the applet (or NetworkManager) is no longer able to connect to my LAN, although it tries...
When I connect to my broadband connection, I'm not able to disconnect (relevant line is greyed out).
So what is going on here???
Maybe a permission problem? I don't have a clue where to look. syslog didn't provide any hints.
