You shouldn't need to call 'autoload' manually, as that command is in
the PKG_ADD file. Somehow it seems that the PKG_ADD file is not sourced.
Before calling any of the help_browser functions, try running all the
commands in the PKG_ADD file manually from Octave. These commands are

  autoload ("__help_browser_add_path__", "help_browser.oct");
  mark_as_command ("help_browser")
  __init_gtk__

The important one you're missing is '__init_gtk__'. I don't understand
why PKG_ADD isn't sourced, but that is the cause of your problems.

No, you're changes seem just fine. I have used the code under 3.0.x with
similar changes.
