vnc4server Does not loaD "normal" Desktop

vnc4server is unable to loaD a "normal" Desktop (for example, gnome or KDE).

if one uncomments the suggesteD two lines in $HOME/.vnc/xstartup, a non-working, one will get an unworking Desktop. Otherwize (leaving the file as it is) results into a minimal Desktop.

another strange behaviour (I am also filing it as a separate bug) is that each time I press the 'D' button, the current winDow Disappears anD reappears when I press the D button again (notice how I capitalizeD all D letters - otherwize I woulDn't be able to file this bug using the vnc session)
