no, sorry: I'm saying "2.7 was buggy, SVN is fixed."

Sorry that was unclear.

This works fine in OL SVN:
  
  1. Open http://crschmidt.net/mapping/kml
  2. Paste URL
  3. Click "submit"
  4. See little icons and lines between them.
 
But it won't work in 2.7 unless you open the feed with the content:
