           Summary: FILESAVE PPTX Creating hyperlink to a slide with
                    shortened name results in invalid file

Example file from PowerPoint

Attached PP-made file contains a slide with a too long title that is shortened
to Slide 1 and another slide with a shorter title.
There is a hyperlink on the first slide to the second, this opens and
roundtrips correctly.
If I create a new internal hyperlink pointing from the second slide to the
first, filesave to PPTX will create an invalid file.

As a counter test I’ll attach another version of the example file with shorter
title that is not shortened to Slide 1.
Creating an internal hyperlink from the second slide to the first creates a
valid PPTX with correctly working hyperlink.

Steps to reproduce:
    1. Open attached file
    2. Go to the second slide, select the text in the lower half.
    3. Press Ctrl+K to open the Hyperlink dialog, select Document on the left
    4. Press the Target icon under Target in Document
    5. Select “Slide 1” in the dialog, press OK
    6. Save as PPTX, open the file in PowerPoint

Actual results:
PowerPoint finds invalid contents in the file.
Reopening the file in Impress also loses the hyperlink just made.

Expected results:
Working hyperlink, no invalid contents.
