problem with desktop icons
 

hi all
i have ubuntu 10.4
i have the following problem:
the desktop icons disappears
and the menu when i use the mous right click too
also, when i try to open any folder i get the following message:
thnx for any help before reinstalling the os :(

Are you running Ubuntu or Kubuntu? kfmclient seems to the a KDE/Konqueror thing.

I suspect you can deal with this without reinstalling the entire system, but we need a little more information about your setup.

Shot in the dark: Run Synaptic and check whether it reports an broken packages in the status line at the bottom of the Synaptic window.

i am using ubuntu and gnome as desktop environment
any help
