Sorry, the bug system email ended up getting spamfiltered so I didn't see them. I've added some whitelisting.
I did an apt-get dist-upgrade right before I filed the bug. I've just done another one, and pulled in a new python 2.7, but it didn't help: I'm seeing the same error. Is there any specific info you want from /var/log/apt/history.log ? Should I attach the whole file, or grep for something in particular? ...Akkana
