Alan, make sure you upgrade properly. Right now you have packages installed with different versions. The fixes to NetworkManager to *avoid crashing* with ipw2200 have landed in Precise already; so running a full upgrade will likely fix this.
This doesn't mean that everything is fixed however; WPA-secured networks will still be unavailable for connection, because there is no way to tell whether the device supports it if the driver reports it doesn't. This needs to be fixed at the kernel level.
