works for me.  Darwin, gtk+ 2.2.4, gtk2-perl HEAD, as well as Linux 
gtk+ 2.6.2, gtk2-perl 1.072 (last thing i compiled against gnome 2.9).  
test program below.

Are you sure that the TextBuffer to which you're connecting the signal 
is the same one that's attached to the TextView when you are editing?


#!/usr/bin/perl -w

use strict;
use Glib ':constants';
use Gtk2 -init;

my $window = Gtk2::Window->new;
$window->signal_connect (destroy => sub {Gtk2->main_quit});
$window->set_default_size (400, 300);

my $textview = Gtk2::TextView->new;
$window->add ($textview);

my $n;
$textview->get_buffer->signal_connect (changed => sub { print "changed! 
".(++$n)."\n"});

$window->show_all;
Gtk2->main;
