Is it possible to attach the document or a link to it so I can test?
Comment 2 KDamian 2014-12-23 07:50:13 UTC 
Yes, sure thing, here is a presentation I've tried to open (too big for attachment, I'm linking to Google Drive); Calligra crashes on 8th slide, if crash does not happen then on 10th.

https://drive.google.com/file/d/0B9B2iJCN0-olQm5FNzFIbHJQbXM/view?usp=sharing

Now I must say that crash happens about 1/10 of the time now (sometimes more often, sometimes less), v. 2.8.7.

Seems like a bug in phonon to me.

The only possible solution I see at the moment is to disable the thumbnail
