Re: invalid image halting rendering in cairo

[Alexander Rakoczy]

So, I think I know what the problem was, and I think this may help others.

In an app like this:

Shoes.app do
  stack do
    image "http://example.com/garbage.png";
    click { info 'cliqued !' }
  end
  para "This won't show up!"
end

wherein, for whatever reason the image fails to load (in this case,
it's not a real png), not only does the click listener not work, but
the application stops rendering.  This only happens the first time you
run the app, because next time the URL will be in the shoes image
cache database (even though no file will be), and the image will just
fail to load properly.
