What version of WLM and MP!L are you using?
Try changing this:

function ShowPanel() {
    var wFirst = MsgPlus.CreateWnd("windows.xml","WndAbout");
    for(var e = new Enumerator(Messenger.CustomEmoticons); !e.atEnd(); e.moveNext()) {
        var Name = e.item().Shortcut;  var Path = e.item().PictureFile;
        var item = wFirst.LstView_AddItem("ListView", Name);
        wFirst.LstView_SetItemText("ListView", item, 1, Path);
    }
}

with this:

function ShowPanel() {
    for(var e = new Enumerator(Messenger.CustomEmoticons); !e.atEnd(); e.moveNext()) {
        Debug.Trace("Path "+e.item().PictureFile);
    }
}

And see what does Debugger says
