Comment 18 for bug 604872

Ok; the commit you point at is in the current qemu-linaro package

Fix released in Ubuntu is when we upload a fixed source package to the Ubuntu development release

The usual way to close Ubuntu bugs fixed with an upload is via the debian/changelog, when Launchpad processes the .changes file with the list of fixed bugs, it marks these fix released

If we need to track status in stable releases of Ubuntu, we use "Target to series" to flag the ones where we need a different bug state
