I don't see this as the problem. The bug is, that the grid-align feature acts 
on the iconArea set in KDIconView which was always changing when the 
KWinModules workArea changed. As Aaron said, we need an area for icons 
independent from the workArea.

I now have solved this and other bugs by introducing a dcop-kicker method 
which allows to request the free space on the desktop not covered by any 
panel - even if the panel is hidden.
I checked this with Aaron and have already commited the kicker modifications.

Now clearly there has to be changes in desktop.
I made the following changes:

As the problem with the icon position on relogin + grid-auto-align is due to 
the fact that kicker starts after kdesktop, I had to introduce the following:
desktop asks kicker via DCOP for the desktopIconsArea. If there is no response 
during 2 seconds and the desktop is currently initializing, I start a timer 
with 15 seconds max. timeout.
During that time, I do not align the icons on the grid, but when kicker tells 
me the iconArea, I stop the timer (or if there is no kicker, I still have the 
timer firing, which would then lead to getting the desktops size).

Regarding this I also had to modify the desktop a bit, e.g. to no longer store 
the icon positions in a relative-to-the-iconArea way (as on startup I do not 
know the iconArea and this relative-storing was ugly at all), but simply in 
absolute coordinates. During this, I also solved the problem, that on 
desktopResize (XRANDR) the icons did not recover their resolution dependent 

Attached you find the patch.
Is it ok to commit ?
