Rawhide/F11 install report: install fails without exception save opportunity

["G.Wolfe Woodbury" <ggw wolves durham nc us>]

The VNC install failed quietly with the only culprit to finger being a 
python assertion error:

python: Modules/gcmodule.c:242: update_refs: Assertion\
  `gc->gc.gc.refs == (-3)' failed.

Then it simply kills the VNC and reports an installer error.
