I experienced the exact same problem. A recent fresh install of Edgy Eft Kubuntu resulted in days of frustration trying to use the Print Manager, CUPS (localhost:631), foomatic-gui, and anything else I could think of to get printing to Letter.
Finally I happened across a google to check /etc/papersize and lo and behold, it was set to A4.
Note, however, that while this is related to libpaper1, /etc/papersize is not included in it according to dpkg -L:

Therefore I am concluding that the installer must dump this file in there. I will file a new bug accordingly and link to this.
