Selecting a wireless network fails instantanously

[Anmar Oueja]

Binary package hint: network-manager

After I updated today's update at approximately 21:43 UTC 20090406, I had to restart (there was no kernel update) the network-manager package requires a restart.

Now when I select a wireless network, I get a "Wireless network disconnected" instantly. I used to use intrepid but updated to Jaunty when Beta was released.

Reported as fixed by the original reporter; closing as Fix Released. This was caused by some version mismatch between the NetworkManager daemon and nm-applet.
