Hi,


I'm using the package pdf-tools to view PDF files. However the popu-menu does't work in recent emacs snapshot. I find it is due the automaticly lowering the menu-bar by easy-menu-deine. Is it a feature or bug?


Of pdf-tools (from melpa or from http://github.com/vedang/pdf-tools/), in the pdf-misc.el it defines
```
(easy-menu-define nil pdf-misc-menu-bar-minor-mode-map
&nbsp; "Menu for PDF Tools."
&nbsp; `("PDF Tools"
&nbsp;&nbsp;&nbsp; ["Go Backward" pdf-history-backward
&nbsp;&nbsp;&nbsp;&nbsp; :visible (bound-and-true-p pdf-history-minor-mode)
&nbsp;&nbsp;&nbsp;&nbsp; :active (and (bound-and-true-p pdf-history-minor-mode)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (not (pdf-history-end-of-history-p)))]
```
And the responding function
```
(defun pdf-misc-popup-context-menu (event)
&nbsp; "Popup a context menu at position determined by EVENT."
&nbsp; (interactive "@e")
&nbsp; (popup-menu
&nbsp;&nbsp; (cons 'keymap
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (cddr (lookup-key pdf-misc-menu-bar-minor-mode-map
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [menu-bar PDF\ Tools])))))
```

However, it can't find the key of "PDF\ Tools". Instead, I find in the `pdf-misc-menu-bar-minor-mode-map`, that,
```
(keymap
&nbsp;(menu-bar keymap
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (pdf\ tools menu-item #1="PDF Tools"
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (keymap #1#
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (Go\ Backward menu-item "Go Backward" pdf-history-backward :enable
```

It becomes lower case (`pdf\ tools`).


If I change the case, the function works again:
```(defun pdf-misc-popup-context-menu (event)
&nbsp; "Popup a context menu at position determined by EVENT."
&nbsp; (interactive "@e")
&nbsp; (popup-menu
&nbsp;&nbsp; (cons 'keymap
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (cddr (lookup-key pdf-misc-menu-bar-minor-mode-map
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [menu-bar pdf\ tools])))))
```
