After receiving a very informative comment from NetworkManager Dan Williams (see the upstreams linked bugreport: http://bugzilla.gnome.org/show_bug.cgi?id=541816#c2 ), it is very likely this bug is really a combination of one or many mac80211-based driver bugs as well as bugs in wpa_supplicant.
@Brian Pitts, @rihasant, @dnel,@dlgandalf:
You all seem to be using mac80211-based cards/drivers, which makes it even more viable.
The wpa_supplicant patches seemed to have been applied since version 0.6.3-2 (https://launchpad.net/ubuntu/+source/wpasupplicant):
* Add 52_handle_mac80211_mode_switch.patch to enhance handling of mode
switching for mac80211 using interfaces.
* Add 53_give_adhoc_assoc_more_time.patch to give adhoc associations a bit
more time.
Thus, it would be very interesting to hear if this problem persists in the current Intrepid development version (it oughtn't...)! Do we have any brave Intrepid tester that can confirm or approve that these patches have fixed the issue?

Since you are using ipw2200, Bug #75358 may be more appropriate for you. Dan Williams also replied in a similar manner here, but mentions a ipw2200 patch suggestion as well: http://
