I got this problem with Ubuntu 10.04 alpha 4 (32bits)
I also got the problems:
192641 - Gdebi-gtk cannot use proxy with authentication
479391 - version upgrade via update-manager or do-release-upgrade does not work with proxy authentication
So I think this bug could be related to proxy authentification too.
