Comment 0 for bug 870012

I've upgraded from natty to oneiric (sudo do-release-upgrade -d) and this added comments like "disabled in upgrade to oneiric" in /etc/apt/sources.list

The problem is: in Brazilian Portuguese, the comment is "desabilitado na atualização para oneiric" (it has unicode characters). When trying to remove, edit or enable these entries via software-properties-gtk, nothing happens.

Running software-properties-gtk from a terminal, the following errors appear, when trying to remove and enable the entries, respectively:
