Thank you for taking the time to report this bug. The real problem in this case is that X exits or crashes, a new session is then automatically started. To find out why this happens, we need Xorg.0.log for the session that crashed/exited. When the new session is started the old one is moved to /var/log/Xorg.0.log.old. In that file there should be a backtrace or some other error message indicating what went wrong (hopefully). Could you please provoke the bug and upload this file?
