This is fixed by d50f2ab6f050311dbf7b8f5501b25f0bf64a439b, which was included in 3.3-rc1.  F15-rawhide are all on the final 3.3 release or newer, so Fedora should already have this fixed.

There was some follow on commentary upstream, but the issue was low severity and upstream has determined it was not really an issue.
