I don't think this is the problem here. The button isn't staying
in the pressed state, it is staying in the PRELIGHT state - which
happens because once it is insensitive, it will never get the
"leave" event that tells it to return to the normal state.

A workaround would be to do:

  gtk_widget_set_state (button, GTK_STATE_NORMAL);
  gtk_widget_set_sensitive (button, FALSE);

The real fix needs to be in GTK, but I haven't figured out what
needs to be done yet.
