make testでは正常に動作しましたが
以下の設定だと上手くいかないようです

(setq howm-menu-lang 'en)
(setq howm-menu-recent-num 20)
(require 'howm-mode)
(setq howm-search-path '("~/Mail"))
(setq howm-file-name-format "%Y/%m/%Y-%m-%d-%H%M%S.howm")
(setq howm-list-title t)
(setq howm-view-grep-log "~/.howm-log")
(setq howm-view-kill-buffer nil)
(setq howm-view-summary-persistent t)
(setq howm-kill-all-enable-force t)
(setq howm-view-summary-shell-last-file "FILE")
(setq howm-view-summary-shell-hist
'("rm -f FILE"))
(setq howm-menu-name-format " *howmM:%s*")
(setq howm-menu-top nil)
(setq howm-menu-file "~/.howm-menu")
(setq howm-menu-expiry-hours 2)
