When saving attachment 172608 [details] from bug 142645 as PPTX the Title slide placeholders internal type changes.
Bug 142645 complains about the Navigator not showing the first slides title as slide name.
After saving by Impress, this changes because the Title placeholders type changes.
Steps to reproduce:
1. Open attachment 172608 [details]
2. Save as PPTX, reload
The Navigator shows the Title placeholders text as Slide name.
The Navigator should not show the slide name being equal the slide title (until bug #142645 is not fixed).
