New issue 400 by aleks.dimitrov: LayoutHints don't respect windows' hint  
changes without changing the workspace state
http://code.google.com/p/xmonad/issues/detail?id=400

What steps will reproduce the problem?
1. Use a minimal configuration like: main = xmonad $ defaultConfig {  
layoutHook = layoutHints (XMonad.Tall 1 (1/2) (3/100)) }
2. Open Rhythmbox and press CTRL-D (to collapse the view to 'compact view')
3. Change the workspace state (toggle struts, change focus, launch stuff)

What is the expected output? What do you see instead?
I'd like XMonad to recognize Rhythmbox' state change without re-evaluation  
of the workspace state. XMonad however doesn't seem to be notified of  
Rhythmbox' preferred size, or maybe just doesn't react to it.

Here's a couple of screenshots to illustrate the problem:

First image shows what happens when RBX changes its appearance and XMonad  
doesn't react (these huge grey windows are exactly what I'm trying to avoid  
using hinted layouts.)
Second image shows the desktop after a state change. That's what I'd like  
to see!
Third image shows RBX expanding to its extended view again, but the window  
doesn't get bigger! It stays small and requires a workspace state change to  
go back to normal.

What version of the product are you using? On what operating system?
xmonad 0.9.1 (Ubuntu 10.04)

Are you using an xmonad.hs?  Please attach it and the output of "xmonad
--recompile".

Minimal reproducing config:

> import XMonad
> import XMonad.Layout.LayoutHints
> main = xmonad $ defaultConfig
>                 { layoutHook = layoutHints (XMonad.Tall 1 (1/2) (3/100)) }

xmonad --recompile remains silent :-)
