new wlan configuration created, although required configuration already exists

[Borim]

os: Ubuntu 12.04

I use a wlan with hidden ssid and wpa encryption. For connecting to the wlan I use the network indicator in the top right corner of the desktop. Sometimes when I connect to the wlan, a prompt appear, asking me for the passphrase. As I know the stored passphrase is correct, I abort the dialog.

The problem is, whenever this happen, a new, blank configuration for the wlan is created. It have the same name, as the correct one with a "1" added.

I expect that if I click abort, nothing gets changed and no new configuration is created.
Also I wonder why a new configuration is created at all. When I enter a new passphrase I expect, that it is stored in the existing configuration.

This happened to me today too. I did not happen before the upgrade to kernel 3.2.0-29. I noticed that my wireless icon in the notification area is also grayed out even though I am connected. Also noticed that my wireless network name is not showing as connected under the "Wireless Networks" section. It is showing in the wireless network list.
