Closed Unassigned: xData.responseXML for GetList returns "Unspecified error" in SharePoint 2013 [10212]

I really love SPServices, so i hope identifying this issue will help to keep the quality of this library.

Implemented Javascript libraries:
jquery-1.10.2.min.js
jquery.SPServices-2013.02a.js

I try to get the rootfolder name of a document library. It works like a charm in SP 2010.

Within SP 2013 i have the following problem:
xData.responseXML returns an "Unspecified error"

xData itself returns a success status and xData.responseText contains the expected value.

```
var currentFolderPath = "";
$().SPServices({
operation: "GetList",
async: true,
webURL: "/",
listName: listName,
completefunc: function (xData, Status) {
$(xData.responseXML).find("List").each(function() {

currentFolderPath = $(this).attr("RootFolder");
});
}
});
```
