I have reproduced this bug in the course of a routine upgrade to my main not really very unusual lenny box. I have a reproduceable test case for a /var/lib/dpkg. I'm not attaching that to this bug because I intend to fix it but if I haven't done so soon please ping me and I will upload the relevant files.
As a workaround I would recommend --abort-after=10000 which managed to get me out of the hole. Ian. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
