We were confused because the failed open should be an IOError. If Image 
is indeed converting such to RuntimeError, it should not. It should just 
let the original error bubble up. It is possibly tossing information in 
the process. The first thing I would do is to look at the code around 
that line in image.py and remove the exception replacement if there is one.
