It seems that if only a single map is specified then emacs just resuses it rather than creating a copy of it. Thus use make-sparse-keymap to force a copy. --- pseudomyne and the diredful author thamer found that we modify widget-keymap in notmuch. We clearly don't want to, and I think we tried not to, but emacs was being clever and reused the old keymap rather than creating a new one. Anyway the following patch seems to work, and if the user modifies widget-keymap deliberately then it does get inherited by notmuch-hello (which was the point of make-composed-keymap rather than just copy-keymap in the first place). The bug only occurs in emacs24. I essentially only use emacs23 so it has not been tested much.
