Hi,
I'm having the same problem. I just found this thread and already asked about it on another forum:

I'm also using fedora 14 with gnome.
Can you guys not even drag and drop one item via the bottom panel bar? It works for me one time after I login and then nothing. Except if I drag and drop from window to window directly..
Maybe this should go to bugzilla...
