Have you confirmed this issue in a different host as well?

There is a lot of stuff going on between your UI and the plugin
instance, especially in a client-server host like Ingen.  Do you mean
your widgets are not receiving events whatsoever, as verified *in the UI
alone*, or they aren't getting all the way to the plugin instance?

The former problem is much smaller in scope.  The problem may not be
related to your code or Gtk signals at all.
