i cannot reproduce this bug using piuparts from squeeze or wheezy, or even today's (2012/07/29) git. i would like to reproduce it to fix it. piuparts-0.46~201207110011~0.44-8375-g38d4cb7 was used for this report, but is not avaiable, i think current version running on piatti should be avaiable so we can check packages against it.
