So if we leave out all the redundant things (and add at
least basic sanity checks), this will remain:

    GtkTextBuffer *textbuffer;
    gchar *buf;
    const gchar *errpos;
    GError *err = NULL;
    gsize n;

    if (g_file_get_contents(filename, &buf, &n, &err)) {
        if (g_utf8_validate(buf, n, &errpos)) {
            textbuffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(textarea));
            gtk_text_buffer_set_text(textbuffer, buf, n);
        }
        else
            g_printerr("Invalid byte at position %d\n", (gint)(errpos - buf));
        g_free(buf);
    }
    else {
        g_printerr("Cannot read %s: %s\n", filename, err->message);
        g_clear_error(&err);
    }

This works, and if it doesn't it will tell you what's wrong.
