I'm using MultiToggle so that I can press WIN+D to toggle on window decorations when I need to tell similar windows apart. However, I've found that this causes a segmentation fault whenever I use it on a tabbed layout. I assume this is because it's already decorated? I know it may not make much sense to decorate it twice, but I don't think it should segfault when I do this. I've tried to get updated versions from darcs, but I don't really understand how all the dependencies work, so I probably did something wrong. I'm running Ubuntu and I believe I installed GHC using apt-get. I can't remember how I originally installed Cabal, but I did "cabal install X11" and so on to install the dependencies listed in the readme. I synced up xmonad and XMonadContrib from darcs today and rebuilt them and installed them using the "--user" option. The crashes still happen. What should I do next? In terms of experience my Haskell is pretty limited, and my knowledge of package management in Haskell is next to zero. I know my way around a command-line so I hope I'll be able to follow any instructions without too much trouble, but I might need things spelled out for me, particularly if it involves editing (or explaining!) my xmonad.hs file. My xmonad.hs file is attached.
