My debian-menu.xml is missing

Question

I have a relatively new Debian installation -- when it was first installed, it was without a gui, but I ran apt-get install xinit and apt-get install openbox, so when I run startx I get an openbox session.

My openbox menu is rather limited, and .xsession-errors shows

Openbox-Message: Unable to find a valid menu file "debian-menu.xml"
Openbox-Message: Unable t o find a valid menu file "/var/lib/openbox/debian-menu.xml"

When I check /var/libopenbox/debian-menu.xml there's nothing there. Is it possible to fix it so that openbox can show debian menu items?

Edit:

The following is an excerpt from my ~/.config/openbox/rc.xml file:

<menu>
  <!-- You can specify more than one menu file in here and they are all loaded,
       just don't make menu ids clash or, well, it'll be kind of pointless -->

  <!-- default menu file (or custom one in $HOME/.config/openbox/) -->
  <!-- system menu files on Debian systems -->
  <file>/var/lib/openbox/debian-menu.xml</file>
  <file>debian-menu.xml</file>
  <file>menu.xml</file>
  <hideDelay>200</hideDelay>
  <!-- if a press-release lasts longer than this setting (in milliseconds), the
       menu is hidden again -->
  <middle>no</middle>
  <!-- center submenus vertically about the parent entry -->
  <submenuShowDelay>100</submenuShowDelay>
  <!-- time to delay before showing a submenu after hovering over the parent
       entry.
       if this is a negative value, then the delay is infinite and the
       submenu will not be shown until it is clicked on -->
  <submenuHideDelay>400</submenuHideDelay>
  <!-- time to delay before hiding a submenu when selecting another
       entry in parent menu -->
       if this is a negative value, then the delay is infinite and the
       submenu will not be hidden until a different submenu is opened -->
  <applicationIcons>yes</applicationIcons>
  <!-- controls if icons appear in the client-list-(combined-)menu -->
  <manageDesktops>yes</manageDesktops>
  <!-- show the manage desktops section in the client-list-(combined-)menu -->
</menu>

Answer 1

The menu package provides the Debian menu and must be installed.

Answer 2

By your description, it looks like the openbox package doesn't operate correctly if the menu package is not installed before it. The easy fix would be for it to Depend: on menu. As Openbox is a light-weight window manager intended for small systems that may not want menu, it would be better to fix Openbox's configuration. Please check whether you can reproduce this issue on a pristine installation of Openbox (save your configuration files and purge the package). If you can, please check the Debian bug tracker to see if this issue has been reported, and if not, report it.
