Comment 3 for bug 778424

Also note that once translations for a distro series have been initialised (even partly, i.e. with an unfinished script run), we should not allow the script run to be requested again (it will fail anyway, but it'd be bad UI to offer something that we know is going to fail).

I agree with Jeroen: this should be part of the entire "create new distroseries in Ubuntu" dance that someone (LOSAs) already do.
