I think I've got the same bug. I've got only 1 workspace (don't like the concept) and I am NOT using desktop effects (compiz). On Intrepid final.
Suddenly Window List looses all windows (becomes empty). If I go to the Preferences and switch to "Show windows from all workspaces", I can see the windows again in the list. Switch back, and they disappear.
