Edit: See newer comment above. A new version is uploaded to address the dialogue crashes.
Yes, from all the reports I've gotten it seems to be something regarding loading resources during dialogues. I can't reproduce it myself, but I have a few ideas for possible solutions that I'll hopefully be able to send to somebody who can reproduce it to see if those solutions actually fix it.
In the meantime, I can't guarantee that going through dialogues slowly will fix it, but it couldn't hurt to do so I suppose.
