I'd forgotten this bug report was here. I found that reverting this patch fixed it for me (ath9k)

                - (can_scan): remove old madwifi hack for not scanning while connected

And I had mentioned it here
http://mail.gnome.org/archives/networkmanager-list/2009-January/msg00107.html
but forgot about it afterward. Then at some point I wiped out my SVN tree and pulled the new NM source from git, and ran into the same problem all over again.

I still believe scanning is a bad idea when you're already associated to an AP. I would guess in the cases where you're walking around a campus and the potential exists to roam between multiple equivalent APs, you could have a setting that says "scan when idle" or somesuch, e.g. when the screensaver activates. But in a lot of common cases, scanning while connected is just a waste.
