fwiw, i'm getting thread destroyed while using cpfind as well.  More 
interestingly, using the gui, and the image tab, "create control points' you 
can see it's finding cp points and then when it's finished it quits, dumps out 
a message 0 control points found.

Doesn't Ubuntu install apt-listchanges by default? I would strongly

recommend to install it and set it up to only show NEWS files.



It would have shown this upon upgrading to hugin 2010.4.0:



------------------------------------------

hugin (2010.4.0+dfsg~beta1-1) experimental; urgency=low



  Starting with 2010.4.0 the hugin suite of program also includes a

  (patent-free) control-point detector. autopano-sift(-c) et al are not

  necessary/nice to have anymore.



  If hugin does not offer cpfind as control-point detector after

  ugrading to 2010.4.0, please open the respective configuration dialogue

  (File->Preferences->Control-Point-Detectors) and use the [Load Defaults]

  button to update the list.
