Yes - I had this too. The problem lies somewhere in the config files for Sawfish or Gnome in your home directory. Try renaming the sawfish folder, then logging on again. If this doesn't work, do the same with the .gnome folder - though you will, of course, have to go back to a default gnome desktop and lose all your customisations. I can't remember which worked for me, but is was definitely one of the config files.
