Here is a screen capture of the blocking Debconf dialog that appears during the upgrade on an amd64 system (I have upgraded 2 computers so far and have not seen that on the i386 one): this is during the libc upgrade. At that moment the glibc does not seem to be available (I have not been able to launch the usual screen capture applications because Gtk relies on glibc so I did use xwd for the capture), so that's probably the reason of the Debconf dialog downgrade. Combined with #663457 this is a major issue on netbook systems.
