There are (at least) two bugs that look rather similar:
bug 658458 and bug 658581
In both cases removal of xserver-xorg-video-nouveau was reported as solution by the affeced persons.

Can you check if you have xserver-xorg-video-nouveau installed?
If you have, can you try to remove that package and start the upgrade again?
