Thanks, your method works. However, it still takes the program quite a bit
to load up, and my problem is that I want display the window as soon as
possible. If that helps, here is how the program loads up:
Script starts
The window is constructed
Window events are connected to their handlers
window.show_all()
When the window is ready, TED Talks are loaded and processed.
Then, widgets for the talks are created. In the widget's constructor, I
call GdkPixbuf.Pixbuf.new_from_stream_async.
Problem: The window does not show up when loading the images (something
that I hoped _async would make possible).
