XEmacs 21.4 (patch 17) へ package でインストールしています

以前の CVS で上げたタイミングが不明なのですが、
1/28 に上げたところ、draft が送信出来なくなりました

Backtrace は以下の通りです

Signaling: (void-function read-event)
read-event("Send current draft? <y/n/j(down)/k(up)> ")
byte-code("..." [scroll-by-SPC prompt cursor-in-echo-area G51317 discard-input t read-event (?y ?Y)

どの様に対処すればよいのでしょうか?
ご教示いただければ幸いです
