You have been subscribed to a public bug: I used "ubuntu-bug xorg" to report this, just in case there is something useful it in. I'm not sure of the root cause.
The only thing I can go off of is this message in my dmesg at the time of the crash: [322186.773973] ecryptfs_decrypt_page: Error attempting to read lower page; rc = [-4] [322186.774015] ecryptfs_readpage: Error decrypting page; rc = [-4] According to bug #509180 that message is necessarily ecryptfs fault, but instead ecryptfs being verbose when it sees something else wrong.
