The problem is that there are two parts in mozilla-bonobo. The plugin
which is a shared library interacts directly with the browser and the
viewer launched by the plugin. The viewer, in turn, loads the bonobo
control. The plugin opens two pipes which are the stdin ad the stdout of
the viewer on startup. The stdin pipe is used to pass everything (uri,
data and params) to the viewer. The other pipe is not used as far as I
know. So when you click, you don't access the plugin but the viewer.
