Comment 1 Stanislaw Gruszka 2011-06-30 19:24:06 UTC 
Do you have steps to reproduce? Or this happen once in random.
Comment 2 Ondra Pelech 2011-07-01 00:42:53 UTC 
I'm terribly sorry, but I can't even properly remember what caused this. I was perhaps twiddling with the NetworkManager (through GNOME3 shell).
Comment 3 Stanislaw Gruszka 2011-07-01 10:06:00 UTC 
Ok, this warning is pretty innocent so I'm not going to investigate this issue, also because there is no clear way to reproduce it.  However I belie we already fix all such issues in upstream code, so the next release will not have this warning.

You can install upstream driver using compat-wireless
http://people.redhat.com/sgruszka/compact_wireless.html
Let me know if you can reproduce issue there (or have any other problem with the upstream driver)
