I had this similar situation where ctrl+alt+left would jump two workspaces to the left each time. Similarly for right.
I fixed it by going to gconf-editor, /apps/compiz/general/allscreens/options, and removing the value 'wall' from the key 'active_plugins'.
I'm guessing this is a conflict between "wall" and "rotate" handling the "left_key" and "right_key" keys.
I noticed this because when I changed the value of "left_key" in "wall", it also changed "rotate_left_key" in "rotate".
I have no idea what I'm doing, but I'm glad I have this fixed.
