unless I'm wrong the GtkTextView widget sets this event_mask:

 (GDK_EXPOSURE_MASK            |
  GDK_SCROLL_MASK              |
  GDK_KEY_PRESS_MASK           |
  GDK_BUTTON_PRESS_MASK        |
  GDK_BUTTON_RELEASE_MASK      |
  GDK_POINTER_MOTION_MASK      |
  GDK_POINTER_MOTION_HINT_MASK |
  GDK_STRUCTURE_MASK)

so it should be delivering motion events even if the mouse button is not
pressed. Are you sure that your window is focused at all before you press
a button in it? You might be tricking yourself with a click-to-focus WM
policy.

did you try the following yet:

  gtk_widget_add_events (GTK_WIDGET (text_view), GDK_POINTER_MOTION_MASK);
