The application nautilus has quit unexpectedly.

["james pruett" <gpscruise gmail com>]

Hi kind souls.

I lost my panels somehow.

Fedora Core4
The application nautilus has quit unexpectedly.
The application gnome-panel has quit unexpectedly.
Ive detected a panel already running, and will now exit.

Its been like this a month or so, so I dont recall what might have caused it.
I am more interested in fixing it.

Any help appreciated.
