Adding ListViewWebPart with CSOM

I have to add a few webparts to a default page using the Client side object model. For the most part this goes fine, I can add a XSLT and content query webparts.

However, when i try to add a ListViewWebPart, I get the exceedingly helpful "Unknown Error" I use the following code to add the webpart

        Microsoft.SharePoint.Client.File oFile = context.Web.GetFileByServerRelativeUrl(newWeb.ServerRelativeUrl + "/default.aspx");
        LimitedWebPartManager limitedWebPartManager = oFile.GetLimitedWebPartManager(PersonalizationScope.Shared);

        WebPartDefinition webDef = limitedWebPartManager.ImportWebPart(webPartXmlString));
        limitedWebPartManager.AddWebPart(webDef.WebPart, "Right", 0);
        context.ExecuteQuery();

and the following XML

</WebPart>

The XML is generated by exporting a sharepoint list webpart, and i can import it through the Gui just fine. (Naturally the {GUID} is replaced with the actual List Id)

Does anyone have any idea what could cause the Unknown error, or at least how i could debug this?
