In some cases, `org-agenda-buffer` is killed while the symbol itself is still non-nil. `org-agena-new-marker` and anything that calls it would end in a message of "Selecting deleted buffer". This commit simply added an additional test that (buffer-live-p org-agenda-buffer) should also be true. P.S. I've sent another patch with the same subject a few days earlier. But that contains an error. Please dismiss that one.
