Same problem here. [CAUTION: Possible spoilers ahead]
I went to Ole through Ima's chamber, went through the first talk animation, filled her first heart, then the second talk animation started and the last thing I can remember was a zoom in on her face and a line of text "won't you tell me? you can't? pity." or something similar. Then it switched to a zoomed out camera again, she turned her head towards me and for a second and it looked like she's about to say something and then her head just snapped to the previous position, looking sideways. The game didn't freeze, and by that I mean she was still moving slightly and the leaves were falling all around, but there was nothing I could click on, and none of the keys did anything, not even the esc key. I'm not really sure about all the details up to the "head snapping" point since it was some time ago, in the meantime I alt-tabbed out of the game, googled around, and eventually stumbled upon this forum. After leaving the game alone I hoped she would snap out of it, but eventually had to end the game with alt+F4.
I attached a zip file containing the "game.log" file (I didn't start the game again so I guess it's the one you might need). Here are the last few lines from it:

Also, some specifics about the gameplay so far (as much as I can remember):
I'm at cycle 22. I have gathered 12 hearts so far. I have opened all of the sisters' chambers except the top left one and Ole, as I just gained access to Ole's main room through Ima's chambers. Of all the big monsters, I only killed the Pangolin so far. I haven't fought any of the brothers yet, the nameless sister died, I already chased the silouhette of a woman on the roof. I met the two sisters that seem to appear randomly, the one with the fan and, more recently, the one surrounded with black smoke. I filled the first heart of the first one and killed the second one with a vampire glyph. Not sure if all of this helps, but maybe you'll be able to localize the problem better.
Anyway, any help would be appreciated.
In the meantime, I'll reload an earlier save, and redo some things I wanted to do in a different way anyway.
