I have seen a similar bug report for ecryptfs+ext3 as well. In fact, a lot of bug fixes were merged for ecryptfs during 2.6.34 development cycle. Perhaps, those fixes were also back ported to 2.6.32, but Ubuntu 9.10 has 2.6.31, so it does not have them, and without them, it looks like a beta-quality filesystem. So, make sure you have regular backups!
