uxa_acquire_solid() can return 0 for all manner of different reasons, if it could not create a solid picture. Yet the return value isn't checked before dereferencing it. Looks like this code has been there for a while, and doesn't appear to have been fixed in the upstream codebase (at least, there's no null pointer check).
Perfect mario, that points to the cause of the crash:
