I just did an apt-get dist-upgrade today. This gave me a new kernel. (Linux malbec 2.6.28-13-generic #44-Ubuntu SMP Tue Jun 2 07:55:09 UTC 2009 x86_64 GNU/Linux).
After this upgrade the wireless network seems a bit unstable.
One other thing I noticed is that KNetworkManager now shows the same network multiple times (screen dump attached). This makes finding the correct network almost impossible.
Below is the output of iwlist wlan0 scan:

PS.
One other new thing, I noticed about KNetworkManager, is that the icon for "secure"/"unsecure" network has been changed from a locked/unlocked padlock icon into a green/red shield. This is really an improvement! That old padlock icons were horrible. It was very difficult to see the difference between locked and unlocked. However, I think that it is a bit of a problem to give the impression that just because a network uses WEB/WPA that means it is "secure" and equally a problem to give the impression that a wifi network without WEP/WPA encryption means that it is "unsecure".
i can confirm this bug for kde 4.3.0 for
