Created an attachment (id=24364)
 --> (https://issues.apache.org/bugzilla/attachment.cgi?id=24364)
PowerPoint file

Code snippet:

import java.io.FileInputStream;

import org.apache.poi.hslf.model.Slide;
import org.apache.poi.hslf.usermodel.SlideShow;

public class POITest {

    public static void main(String[] args) throws Exception {

        SlideShow ppt = new SlideShow(new FileInputStream("tt2.ppt"));

        Slide[] slides = ppt.getSlides();

        for (int i = 0; i < slides.length; i++) {
          ppt.removeSlide(0);
        }

        Slide newSlide = ppt.createSlide();

    }

}

This code generates following error:

Exception in thread "main" java.lang.IllegalStateException: The last child
record of a Document should be EndDocument, but it was
org.apache.poi.hslf.record.UnknownRecordPlaceholder@12d96f2
    at
org.apache.poi.hslf.record.Document.addSlideListWithText(Document.java:179)
    at org.apache.poi.hslf.usermodel.SlideShow.createSlide(SlideShow.java:700)
    at POITest.main(POITest.java:19)

With removeSlide commented works ok.
tt2.ppt attached (file received from our customer)
