Greetings, monks. I am a novice in both Perl and Gtk, so forgive my ignorance.

I came here to seek help with a strange behaviour of Gtk3 IconViews. Basically, every now and then, my script crashes when I either hide() or destroy() a GtkIconView, with the following error code:

***MEMORY-ERROR***: menu.pl[4944]: GSlice: assertion failed: sinfo->n_
+allocated > 0
Abandon (core dumped)

Here is how the IconViews are generated:

    my $model = Gtk3::ListStore->new('Gtk3::Gdk::Pixbuf','Glib::String
+');

    foreach my $vu (sort @bibliolist) {
        my $pixbuf = undef;
        if ( -f "$path/Miniatures/$vu.jpg" ){
            $pixbuf = Gtk3::Gdk::Pixbuf->new_from_file("$path/Miniatur
+es/$vu.jpg");
        }
        else {
            $pixbuf = Gtk3::Gdk::Pixbuf->new_from_file("$path/Interfac
+e/noimage.jpg");
        }
        my $iter = $model->append;
        $model->set($iter,0,$pixbuf,1,"$vu");
    }
    my $view = Gtk3::IconView->new_with_model($model);
    $view->set_property('name','mlist');
    $view->set_selection_mode('single');
    $view->set_pixbuf_column(0);
    $view->set_text_column(1);
    $view->set_columns(-1);
    $view->set_item_width(110);
    $view->show();
    $selectbiblio->add($view);

Is there anything I'm missing? I have to admit I'm completely lost there...

Thanks in advance for your help.
