Oh, the attachment didn't get to the list - This is how I did it:


/**
 *
 */
GdkPixbuf *get_pixbuf_from_icon(GIcon *icon, GtkIconSize size)
{
        GdkPixbuf *result=NULL;
        GtkIconTheme *theme;
        GtkIconInfo *info;
        gint width;

        if (!icon)
                return NULL;

        theme=gtk_icon_theme_get_default();
        gtk_icon_size_lookup(size,&width,NULL);

        info=gtk_icon_theme_lookup_by_gicon(theme,
                                            icon,
                                            width,
                                            GTK_ICON_LOOKUP_USE_BUILTIN);

        if (!info)
                return NULL;

        result=gtk_icon_info_load_icon(info,NULL);
        gtk_icon_info_free(info);

        return result;
}


/**
 *
 */
GdkPixbuf *get_pixbuf_from_file(GFile *file, GtkIconSize size)
{
        GIcon *icon;
        GFileInfo *info;

        GdkPixbuf *result=NULL;

        info=g_file_query_info(file,
                               G_FILE_ATTRIBUTE_STANDARD_ICON,
                               G_FILE_QUERY_INFO_NONE,
                               NULL,
                               NULL);

        if (!info)
                return NULL;

        icon=g_file_info_get_icon(info);

        if (icon!=NULL) {
                result=get_pixbuf_from_icon(icon,size);
        }

        g_object_unref(info);

        return result;
}


Again - thanks guys!
