Have you had any other crashes like this one either before or after? The crash occurs due to some invalid memory situation, but unfortunately it's unclear why it's failing since the stacktrace consists of only a single call. We did have some memory related issues a while back which have since been resolved, so if you've not seen this crash lately and if no one else files similar reports, perhaps the issue can now be closed as resolved.
