Since i have installed new package for Python (language), i have an error message when my session start:

" Cannot start tray. "novfsd" is not running "

after type OK:

" Please start novfsd as root with the command: ' rcnovfsd start' and try starting the tray again "

first, what is the tray how could i start it,because after the command rcnovfsd start and restart the computer, i have the same error!!!
