I've scanned through a whole bunch of the duplicates for this bug. Every single one of them has ecryptfs enabled, and several of them mention being low-ram at the time of the crash.
With those two requirements in mind, I'm currently creating a low-memory Natty VM that uses ecryptfs. Assuming I can easily reproduce the problem there, I'll upgrade the VM to Oneiric and try again.

I'll report any progress back here.
