As far as I can tell by divination from the packages that are being upgraded in these logs, most of the reports of this are from users of Xubuntu Feisty Herd 2 (they all seem to have python-exo installed, for example, and the versions are consistent with Herd 2). I'm grabbing that image from the archives now and will see if I can reproduce it from that.
