And, if you hate that the eventloop wastes CPU power,
---------------------------------------------------------------
require 'tk'
Tk.root.withdraw

def choose_directory(keys = {})
  th = Thread.new{Tk.mainloop} # start the eventloop
  begin
    dir = Tk.chooseDirectory(keys) # show dialog
    Tk.update # for safety
  ensure
    th.kill # stop the eventloop
  end
  dir
end

if __FILE__ == $0
  dir = choose_directory(:initialdir => '/', :title => 'test test
  test')
  p dir
  p choose_directory(:initialdir => dir, :title => 'test TEST test')
end
---------------------------------------------------------------
