	* src/messageview.c
	Fix wrong message, as message could have been moved to another folder
	and not trashed (it could have also be deleted without staying in trash,
	but that's a piece of detail, and while we're at it, the message could also
	have vanished into another dimension or be now part of the twilight zone
	but we should not always tell the truth to users. At last, and to be
	exhaustive, the message could have disappeared because of a technical
	issue which doesn't imply user action and none of the above mentions. One
	would say that the message could also have never existed, but it's another
	story).
