Description Tamás Zolnai 2017-09-21 20:03:06 UTC

Description:
Check the attached document. It's a minimal reproducer created based on a user doc. Somehow there are ODPs which contains subtitle blocks on master slide (I can't see how to create such a document on the GUI). LO can save this into a PPTX and import it back, but it seems MSO does not like subtitles on master slides (allowed on layouts).

Steps to Reproduce:
1. Open attached ODP
2. Save it to PPTX
3. Open it in MSO

Actual Results:  
MSO says the file is corrupted.

Expected Results:
Make export create a document with which MSO has no problem, during opening.


Reproducible: Always

User Profile Reset: No
