We have four reports of this crash, one on the GT-I9100 (running Replicant) and three on the GT-I9300 (probably also running Replicant, as it's the same Android version as the GT-I9100, and the version's too high to be a factory ROM).

This looks like a Replicant bug: camera calls are being made asynchronously. I'll report it upstream. I'm not adding it to the current milestone as there doesn't seem to be anything we can do.
