I don't know. After the second time it happened, I clicked the "delete" button on the error. The error says something about the tomboy applet not loading properly, then asks if i want to delete or not delete the applet from the configuration. The first time I chose "not delete" hoping it was fixed just from the deleting ~/.gnome2/panels.d, but it happened on next boot, so I chose "delete" that time.
