Comment:

 OK, I found a solution. I have no idea why it works :) , I didn't research
 too much about the Elements and Box2D libraries but this patch could be
 tested and understood by others.

 I just remove {{{.getAsType()}}} in the line that fails from the Elements
 library.

 These are the steps to apply this patch:
  1. unzip Elements-0.13-py2.5.egg
 {{{
 cd physics/lib
 unzip Elements-0.13-py2.5.egg
 }}}
  1. download the patch from this ticket
  1. apply the patch
 {{{
 patch -p0  < Elements-0.13-py2.5.egg.patch
 }}}

 That's all. Run the activity again and try this new patch.

 I tested this in XO 1.5 and 1.75 both with os9 and it works properly.
