Hm, not really. That is actually a bug in AMOS. It should not let you translate strings for 1.x version as the maintainer does not have an option to export your contribution and commit it into CVS manually. It was a planned feature but this area has not been finished yet.
I can see two ways how to sort this out:
- either implement a feature that lets the maintainer export the contributed translation into files so they can send it to CVS manually
- or prevent translation of 1.x strings via AMOS
