The warning seems to be a bug from Ubuntu. That bug report:
  https://bugs.launchpad.net/ubuntu/+source/quickly/+bug/853232
suggests that it can be fixed using:
  sudo apt-get install gtk2-engines-pixbuf


But, even with those warnings, the AABB_demo should display a white windows 
*but* with a menu (see the attached screenshot "AABB_demo-shot-empty.png").

Using the File menu, "Load polyhedron...", you can open a data file, for 
example "hand.off". See the attached second screenshot "AABB_demo-shot-
hand.png".
