Hmm, I could not find gtk_block_signal_handler_by_func.
#and I don't know the example what you see.
Is it gtk_signal_connect_by_func?

I think this is Ruby/GTK's problem, but I don't have any ideas now.

I wrote a script same as your code once. 
It works fine for ASCII charcter, but it doesn't work with 
2-byte character(like Kanji).

require 'gtk'

entry = Gtk::Entry.new

handler_id = entry.signal_connect_after("insert_text") do |widget, text, pos|
  entry.signal_handler_block(handler_id)
    entry.delete_text(pos - 1, pos)
    entry.insert_text(t, pos)
    entry.position = pos + text.size
  entry.signal_handler_unblock(handler_id)
end

window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
window.add(entry)
window.show_all
Gtk.main
