Do you have steps to reproduce? Or this happen once in random.
I'm terribly sorry, but I can't even properly remember what caused this. I was perhaps twiddling with the NetworkManager (through GNOME3 shell).
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)
