	Yeah, sorry. Its:

	No, the problem is that they've only changed *some* of their panel
configuration.

	I've updated the bug report with an explanation:

  What's going on here is the panel configuration consists of a large
  set of inter-related GConf keys. Lets think about just two of them for
  a minute - toplevel_id_list and object_id_list. The former contains
  the list of panels in the configuration and the latter contains the
  list of launchers, menu buttons, menu bars etc. (everything but bonobo
  applets).

  These GConf keys individually inherit their default values from
  defaults database. If you set one of the keys, it no longer matters
  what the default is, but the other one still inherits the default.

  So, looking at Stephen's screenshot, its obvious what happened. He
  added a new launcher to his panel at some point, setting
  object_id_list to contain all the default launchers and his new one.
  toplevel_id_list remained unset, inheriting the default. 

  Now, when the panel package was updated the defaults changed, adding
  an extra panel to toplevel_id_list, removing the menu button from
  object_id_list and adding the menu bar to object_id_list. End result
  is that Stephen sees the new panel, but still sees the menu button
  when he should be seeing the menu bar.

Cheers,
Mark.
