Bug Description
Binary package hint: network-manager
NetworkManager appears to fill the essid with garbage when it disconnects from a network as part of disabling networking (ie: right click on nm applet, uncheck "enable networking").
craig@ayaki:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu lucid (development branch)

While connected to wifi, as normal:
root@ayaki:~# iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:"madradish"
Bit Rate=1 Mb/s Tx-Power=14 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=42/70 Signal level=-68 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
After disconnection, note the garbage essid:
root@ayaki:~# iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:"
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
I never noticed this before upgrading to lucid (pre) and therefore from NM 0.7 to NM 0.8 . While that doesn't mean it wasn't happening, I tend to use iwconfig and would expect to have noticed.
It also happens if I disconnect from the wireless using the "Enable Wireless" check box.

.... or even leaving wireless enabled and using the "Disconnect" menu option:
craig@ayaki:~$ iwconfig wlan0 \x05\xEF\ xF7\x00\ xE9\xA1: \xE5\xCA\ x0B\xCB\ xD0HGd\ xBD\x1F# \x1E\xA8\ x1C{d\xC5\ x14sZ\xC5^ Kyc"

I smell a string null termination bug...
