I backed up my home folder and reinstalled Parabola.

I have xfce4 and xfce4-goodies installed.

When XFCE is loaded the xonfiguration is correctly restored except that some plugins are missing:

Mail watcher, Weather update, Commandline, Search, Notes, Screenshot, CPU graph, CPU monitor, eyes, and more. (missing)

Clock, Window Buttons, Notification Area, Filesystem Browser, Power Manager Plugin, Action Buttons and Window Menu are all showing up in the correct placement. (not missing)

I attach my xfce4-panel.xml.
