Comment 89 for bug 199960

I have upgraded to Hardy Heron (04/28/08) . I have the same problem on an irregular basis. When problem occurs, I have ~1 min of dark screen, then gnome gives the error described in this bug. Then starts with "unusual" looking icons and such. The system works but slowly. Once in a while, everything goes smoothly, I do not have the error , I see my usual looking icons and such but things like wireless cards (network-manager) do not work.
