got a strange problem with my ubuntustudio 12.10 quantal release.
I was thinking about to disable some icons from the menu which can be opened from the very left top side of the desktop and started to edit these icons with the GUI given by xfce (dont blame me about the name, i dont remember it).
After disabling some icons the complete panel was gone and shows me an error (see later). The menupanel is still active but im not longer able to open it from the left top side. I got an error message that my desktop is unable to load the menu.
Here is what ~.xsession-errors say:
Sorry for the german logs, ill try to translate it:
** (xfdesktop:2889): WARNING **: Unable to load menu: Fehler in Zeile 1, Zeichen 1: Dokument ist leer oder enthält nur Leerraum
renaming the ~.config/xfce4 doesnt help
** (xfdesktop:2889): WARNING **: Unable to load menu: Error in Line 1, Sign 1: Document seems to be empty or it only contains empty space
