Version: 20081005.1+svn868130-0neon2 (using Devel) OS: Linux Installed from: Compiled sources Can't unlock the session, no matter how carefully I write the password, it always says "unlock failed". So you have to use Ctrl + Alt + BackSpace to restart X server to get computer work again. Unfortunately I don't know how to reproduce it or show a backtrace.
