I investigated this some more. According to jenkins.debian.net, the problem was introduced between 2012-11-27T05:06:19 and 2012-11-28T05:07:29. The first failing log is available from <URL: http://jenkins.debian.net/job/chroot-installation_squeeze_install_gnome_upgrade_to_wheezy/62/ >.
I extracted the set of downloaded packages, to see how these changed to get some idea about the cause of this problem. These are the changed versions between the working and the failing upgrade: --- consoleText.61-short 2012-12-12 20:55:59.000000000 +0100 +++ consoleText.62-short 2012-12-12 20:55:52.000000000 +0100 @@ -724,7 +724,7 @@ wheezy/main libical0 amd64 0.48-2 [238 kB] wheezy/main libicc2 amd64 2.12+argyll1.4.0-7 [162 kB] wheezy/main libice6 amd64 2:1.0.8-2 [63.1 kB] -wheezy/main libicu48 amd64 4.8.1.1-9 [4737 kB] +wheezy/main libicu48 amd64 4.8.1.1-10 [4741 kB] wheezy/main libicu4j-java all 4.2.1.1-1 [5877 kB] wheezy/main libidl0 amd64 0.8.14-0.2 [127 kB] wheezy/main libidn11 amd64 1.25-2 [178 kB] @@ -1321,7 +1321,8 @@ wheezy/main python-pam amd64 0.4.2-13 [14.8 kB] wheezy/main python-pkg-resources all 0.6.24-1 [63.6 kB] wheezy/main python-pyasn1 all 0.1.3-1 [51.4 kB] -wheezy/main python-pyatspi2 all 2.5.3+dfsg-2 [29.6 kB] +wheezy/main python-pyatspi2 all 2.5.3+dfsg-3 [2788 B] +wheezy/main python-pyatspi all 2.5.3+dfsg-3 [30.0 kB] wheezy/main python-pycurl amd64 7.19.0-5 [87.6 kB] wheezy/main python-pyorbit amd64 2.24.0-6+b1 [111 kB] wheezy/main python-pysqlite2 amd64 2.6.3-3 [69.6 kB] @@ -1496,7 +1497,7 @@ wheezy/main xserver-xorg-video-mach64 amd64 6.9.1-2 [216 kB] wheezy/main xserver-xorg-video-mga amd64 1:1.5.0-2 [121 kB] wheezy/main xserver-xorg-video-neomagic amd64 1:1.2.6-1 [48.4 kB] -wheezy/main xserver-xorg-video-nouveau amd64 1:1.0.1-3 [307 kB] +wheezy/main xserver-xorg-video-nouveau amd64 1:1.0.1-4 [307 kB] wheezy/main xserver-xorg-video-openchrome amd64 1:0.2.906-2 [205 kB] wheezy/main xserver-xorg-video-r128 amd64 6.8.2-1 [183 kB] wheezy/main xserver-xorg-video-radeon amd64 1:6.14.4-5 [724 kB] I guess changes to one of these packages caused the upgrade to break. After checking the package changelogs, I suspect the changes in python-pyatspi2 version 2.5.3+dfsg-3 is the cause.
