I had this bug, and I've resolved it (at least for me).
I'm using Kubuntu Intrepid with Proposed updates on a Acer Travelmate 520 with a Linksys Broadcom bcm43 PCMCIA wireless card.
This setup worked fine under Hardy, but I suffered from this bug after upgrade to Intrepid.
A comment above suggested I use nm-applet as a workaround replacement for knetworkmanager.
In order to avoid I conflict, I thought it best to apt-get remove knetworkmanager prior to installing nm-applet. But apt-get reported that knetworkmanger was _NOT_ installed (!?).
So I ran 'apt-get install knetworkmanager' which apt-get reported as installing normally, rebooted, and now it's connecting working fine...
