Hi Debian Qt/KDE
I come back on this bug.
It seems that it has been closed too quickly.
I had to reinstall my debian months ago and I still experience the bug.
I confirm that this bug can only happen with a smp kernel on a multi-processor mother board (I have 2x1GHz Processors).
I will be very glad to hear that you can spend a few time to look at this again.
As usually, If you need more informations, just ask.
