Comment 1 for bug 1495348

I have seen this bug also. I'm running a dual-boot system (elementary on one drive, Windows 7 on a second drive), with a single root partition and swap partition.

The workaround I found was to run the *ecryptfs-rewrap-passphrase* command after mounting my encrypted home directory. I wrote a more in-depth report + answer here: https://elementaryos.stackexchange.com/questions/7947/login-redirects-back-to-login-screen.
