The alt-h scenes aren't crashing anymore with latest fix (0.9.3), but the scene itself causes some graphical bugs midway and even after the scene is over, in some transitions like new scenes or character sprites changes it gets buggy for a very short time. Saving & quiting doesn't solve this, only by starting a new cycle in the menu.
Here are some screeshots from the graphical bug:

From what i've seen, it only happens if the alt-h scene plays and it persists on the cycle after the scene is over.
