Comment 3 for bug 331094

This is probably exacerbated by the fact that we now import Ubuntu translations faster than the build system produces them:

1. Soyuz builds package X for architecture A, uploads its translations.
2. Rosetta auto-approves them, then imports them.
3. Soyuz produces package X for architecture B, uploads the same translations again.
4. Rosetta rejects these because they have the same timestamp as the ones it just imported.
