Comment 7 for bug 137989

Also happens with me, on amd64. Trying to connect to a network will often just crash the applet. A non-broadcasting, WPA2-secured network, if that matters. Only way I've found to fix it is with a total reboot.

dmesg shows me:

Sorry for the length. Thanks for any help, this is supremely frustrating to have to reboot just because my network fails.
