Gtk3::Ex::DBI::Datasheet query() signal problem

[Geert Dobbels <dobbels geert googlemail com>]

Hello,

I started to use Gtk3::Ex::DBI::Datasheet a week or 2 ago and have been 
successful with all I needed until I started to use the query() method 
on an existing Datasheet object.  I tried with and without a 
where_object but always get the same result:

GLib-GObject-WARNING **: gsignal.c:2579: instance '0x85952a0' has no 
handler with id '1496' at 
/home/geert/Documents/proyectos/gladetests/Gtk3/Ex/DBI/Datasheet.pm line 
2014.

The line 2014 is where the signal_handler_disconnect is done in the 
following chunk of code exctracted from Datasheet.pm:

  # Destroy changed_signal attached to old model ...
    if ( $self->{changed_signal} ) {
$self->{treeview}->get_model->signal_handler_disconnect( 
$self->{changed_signal} );
    }


I had a look at the $self object to see if I could find anything wrong 
with it, but could not get anything out of that.  This is a Data::Dumper 
printout of the $self variable right before the above shown chunk of 
code is executed:
