Gtk2::TextBuffer 'changed' signal

[Daniel Kasak <dkasak nusconsulting com au>]

Hi all.

I've just noticed that I'm not getting signals fired on a 
Gtk2::TextView's TextBuffer's changed signal.

I have a GtkTextView widget on a Glade form.
I do the following:

$form->get_widget("MyTextView")->get_buffer->signal_connect ( changed => 
\&some_sub );

Then I have:

sub some_sub {
   print "Hi there!\n";
}

some_sub never fires when I edit the text in the textview. It used to, I 
swear. I've tried with gtk2-perl / glib-perl 1.0.61 and 1.0.42 ( with 
gtk+ 2.6.2 ).

I've inspected $form->get_widget("MyTextView") and 
$form->get_widget("MyTextView")->get_buffer in a debugger - they are a 
Gtk2::TextView and Gtk2::TextBuffer respectively. No errors are thrown.

The above is the correct way of doing it, right?
What's going on?
