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 Additional Info: User-Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36
