What about this, then? Looks like it is commited by you:
http://cgit.openembedded.org/openembedded-core/commit/meta/recipes-core/ncurses?h=kirkstone&id=325fe5f68bc698f78f5c1a14407c0bbb4cba45f7
Indeed, you were updating from a development snapshot to another development snapshot, but judging by the history of this recipe I thought that this was always the case.

If the standard policy is that, maybe the CVE_VERSION line should also be removed.
