This changeset http://hg.mozilla.org/mozilla-central/rev/580018b5f41b removed build/macosx/mozconfig.leopard from mozilla-central. The check-sync-dirs.py test checks if build/ from comm-central and mozilla-central are in sync. Currently mail/config/mozconfigs/macosx32/debug still includes the mozconfig.leopard file. We need to check what to with this file (the Firefox version of that mozconfig got deleted).
