Seems like this is already fixed (at least it seems so in vivid). I'll mark it Fix Released and we can see whether it needs to be updated as SRU in the other releases.
As for Yu Ning's patch, it's appears to be for a different issue, so I'd open this up as a separate bug -- re-adding sources still needs to be fixed.
