In this case your GtkImage just has pixel data, it doesn't know that it
came from a stock icon. How could it? Thus it will not update on theme
changes. You could connect to the style_set signal to detect theme
changes, and update your pixbuf manually in that case.

In this case you've given the GtkImage enough information for it to
automatically update on theme changes. i.e. you passed in the high-level
stock icon information, instead of just pixel data.
