sid network-manager-kde can't processed password

[godo <goran@dobosevic.com>]

Hi all,
I have this problem on my sid box for some time.
network-manager-kde can scan wifi networks and when i chose my router he 
detect right encryption (WPA/WPA2), I type my password, click OK button 
and everything seems fine.

But when i click on network-manager-kde icon and then on the my wifi 
connection he open again password dialog with good password written in, 
when I click Ok nothing happens.
If I don't have password protected router he can connect.

On my other box (squeeze) it works correct.

Can somebody tell me how can I investigate problem?

Thanks in advance.
