This is a bug in GTK+-1.0.5. In GTK+-1.1, gtk_editable_set_position()
calls gtk_entry_adjust_scroll which calls gtk_widget_queue_draw()
on the entry.

(Hmm, I suppose that needs to be merged back for 1.0.6)

So, if you add a line 

  gtk_widget_queue_draw (SignalEntry)

after the gtk_entry_adjust_scroll(), then things will work fine
for now, and will only be doing a little bit of extra work
when the bug fixes get in.

[ BTW - gtk_entry_adjust_scroll should never have been made public. 
  That just covered up for bugs. It will be deprecated for GTK+-1.2. ]
