Comment 2 for bug 415595

This does not seem to be a problem of the finder not finding the .tar.gz:
Looking at the code (http://bazaar.launchpad.net/~launchpad-pqm/launchpad/stable/annotate/head:/lib/lp/registry/scripts/productreleasefinder/finder.py) it seems that only the first matching file is added. All other release tarballs are ignored, see hasReleaseTarball(), addReleaseTarball() and handleRelease().
