Difficult to declare if it is reproducible on other machines when this behavior is present starting from installation of 9.10 RC. It is definitely reproducible on my comp. I can add following comments after some recent tests...
(1) Black desktop is shown just after login.
(2) When trying to change it in Appearance Preferences - Backrounds, then no change is observed. Black desktop screen remains.
(3) I am not sure but it may be an graphic driver problem as hardware acceleration of my card (ATI Radeon 9200 SE) is not working - cca 400 FPS in gear test. (I am going to submit this graphic card problem later today as I am not at home now.)
(4) Both graphic card acceleration and desktop image was OK in 9.04. However, I used proprietary driver offered by Ubuntu which is not offered in Karmic Koala.
