I want to add a comment that this error message can also be caused by a  
wrong xmonad config (I spent some time looking for this). Briefly, if you  
have strictly more xinerama screens than initial workspaces in your xmonad  
config (I use DynamicWorkspaces), then you will see this crash, and it will  
go away if you add more initial workspaces in your xmonad config or if you  
change the screens config using xrandr so that there appear to be fewer  
screens on startup.
