New issue 241 by lucia.culakova: 0.8: moving floated window changes the  
current tiled master
http://code.google.com/p/xmonad/issues/detail?id=241

What steps will reproduce the problem?
1. Create a workspace with 3 tiled and a single float window.
2. Change one of the non-master tiled windows to master.
3. Move the float window around with a mouse.

What is the expected output? What do you see instead?
Nothing happens to the tiled layout, the float window moves. Instead, while
the float window moves, the previous master is swapped back into master
position in the tiled layout.

What version of the product are you using? On what operating system?
This happens in 0.8 from cabal, ghc 6.8.2 on Debian. Downgrading xmonad and
xmonad-contrib to 0.7 fixes the problem.

Please provide any additional information below.

          ]
         )

----------------------------------------

I don't this is due to a contrib module, as this still happens when I cut
down the configuration file considerably.

I recall trying to solve this in #xmonad, but noone has been able to
reproduce, so I am at a loss what's wrong here. But, recompiling xmonad-0.7
against exactly the same system fixes the problem, so I believe this *is* a
xmonad bug...
