Well, I have another comment (holidays are good for that) :
Just after that, I tried with my normal session and the problem came, then in the KDE service manager I unchecked every service and rebooted.
With the next boot, I started to play with konqueror with no problem, I added a few services and still nothing. I then added almost all services with no problem, then I started kopete and still nothing. I started all the services that were not started and fired Amarok (which gave me the problem another day) and still nothing ...
I really don't understand a thing, is there any particular order between starting services and using programs that cause this problem ?
