Created attachment 32233 [details] Corrupted PPT file causing deadlock
The patch.tar.gz doesn't contain a patched class, i.e. there's no patch in the patch.txt nor in one of the subdirs. Please check and attach it again. Btw. Libre Office empties all slides and PPT-Viewer doesn't show it at all.
Thank you for reporting the deadlock. I've applied a patch with r1643680
