I think this is actually the aptdaemon bug #981124 that we are hitting here. I uploaded a fix into precise-proposed and I think it only affects i386, this is why I was not able to reproduce this myself. Could you please confirm that you run on a i386 system (in a terminal you can type: "dpkg --print-architecture").

Had to killall -9 software-center and apport-gtk. After this happened, simply launching the software center caused the crash loop to happen again. Launching and killing it a few times seems to have fixed it. Also, the size of the psychonauts package is reported as 134.9 MB in stead of 4.1 GB. $ lsb_release -rd Description: Ubuntu 12.04 LTS Release: 12.04 Ubuntu Software Center version 5.2.2.2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1011780/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
