Device Notifier

I last used my external hard drive about 2-3 days ago, and device notifier asked me if I wished to mount it. I just tried the same in rawhide, and it also asked. Rawhide is updated to today's status, including kde-4.6. However, in F14, also updated to today's status, including kde-4.6, device notifier no longer recognizes that the external usb hard drive has been plugged in and no longer asks me what I wish to do.
