Writer crashes on close everytime I open a document, manually or programmatically, after having created an instance of a MailMerge object using CLI-uno.

Step to reproduce:
- Create a small C# app that does the following:

            XComponentContext context = Bootstrap.bootstrap();
            XMultiServiceFactory msf = (XMultiServiceFactory)context.getServiceManager();

            //Create the Mail Merge service
            object mailMerge = msf.createInstance("com.sun.star.text.MailMerge");
            ((XComponent)mailMerge).dispose();

            //Open document
            XComponentLoader componentLoader = (XComponentLoader)msf.createInstance("com.sun.star.frame.Desktop");
            componentLoader.loadComponentFromURL(new Uri(System.Environment.CurrentDirectory + @"/test/test1.odt").AbsoluteUri, "_blank", 0, new PropertyValue[] { });

- Close writer.
- You receive an error. Inside Event Viewer you find:

The same error is thrown even if you open a document manually, without using loadComponentFromURL but keeping the test program opened.
