Does it help to paste to other applications if you add

  clip.use_primary_selection

here? Looking at the wxWidgets drag'n'drop sample, this is needed under 
X to share with other applications.

It might be worth checking if the data is at least available within your 
own application. After doing the set_data, trying retrieving it with 
something like

Wx::Clipboard.open do | clip |
  data = Wx::TextDataObject.new
  clip.get_data(data)
  p data.get_text
end

I tried it out on Ubuntu and unfortunately I can confirm that neither 
within-application or inter-application copying via the Clipboard is 
working for me. However I'm using Ubuntu within a VirtualBox VM at the 
moment and this has some clipboard integration with the host OS - so I'd 
like to this out as the source of the problem.
