Is that the only call? If so, I don't understand hy Martin's change
didn't work.

And this is a different segfault from what you've shown before.
Can you step into the call to x_free_frame_resources, then step from
there into free_frame_faces, and see what it does there? You are
supposed to see that image_cache->refcount is at least 2, and
therefore free_image_cache is not called.
