Kubuntu Feisty crash when rebooting or turning off from KDE session

[Rafael Belmonte]

Binary package hint: kdebase

When i try turn off or reboot from a KDE session in Kubuntu feisty fawn, system crash without shutdown screen progress appears (the screen with the progress bar).
My monitor screen turns in to "black" and monitor power LED stays intermittent until i press computer reset button.
But if i reboot or turn off from kdm menu or out of X shell, the system shutdown well.

Thanks for your collaboration. Now does this problem happen on a full upgraded system?
Thanks in advance for your reply.

The problem has been fixed on a full update system, thanks.

The same problem again with a full updated Kubuntu Feisty version.
I use driver "ati" in xorg, if i set "vesa" driver, the problen doen't happen, but using always vesa driver is not a solution.

The problem also desappears if I deactivate usplash and if I erase 'splash' boot option in kernel. The problem is relationed with graphic driver and splash screen.
My graphics card is Radeon 9250 and its optimal driver is "ati" or "radeon" on xorg, and with both of them the problem occur.
