Pierre, what you're seeing are kernel oops, adding a linux kernel task to the bug report. Can you confirm that you don't see these oops if you downgrade libc to the earlier version? e.g.
apt-get install libc6=2.13-20ubuntu5 libc-bin=2.13-20ubuntu5
(You may need to add additonal packages to your apt-get install line, similarly formatted)
