Uh-oh, this looks like it would instead be an issue in NetworkManager, not wpasupplicant. Reassinging.
To clarify what is going on and whether this has already been fixed, would you be able to test this on the latest release of Ubuntu, Ubuntu 11.10 (Oneiric Ocelot) ? You can do this easily by downloading the LiveCD at http://www.ubuntu.com/download/ubuntu/download , and running it without any changes to your computer. Reporting back here with whether the same issue happens would be very helpful in debugging the problem. It would also be useful if you could try to reproduce the problem and attach the file /var/log/syslog to this bug report.
