Comment 6 for bug 548375

You dropped out soon after you asked for my comments on the branch. So, it seems what you are doing is ignoring empty messages on *all* PO file imports. We should not do that, but do that only for "is_imported" or "is_published" ones (those coming from packages). You should be able to upload a PO file with no translation to unset a bad translation. I'd be even more interested to know how did this break, since that's how it used to work. The code for this was in updateTranslation() before.
