What version of GTK are you using? There have been many fixes to the
text widget in recent versions.

Here's the code I use to move to the bottom of a non-Editable text
widget after inserting text:

  GTK_TEXT(text)->vadj->value =
                 GTK_TEXT(text)->vadj->upper -
                 GTK_TEXT(text)->vadj->page_size;
  gtk_signal_emit_by_name ( GTK_OBJECT(GTK_TEXT(text)->vadj),
                  "value_changed");
