Logs with information of the crash

It was observed that xfce4-screensaver can cause a Xorg crash. This crash will make the entire Xorg session close, closing all applications and, due to how the computer is configured, will suspend the system.

Steps to reproduce:

1) Have xfce4-screensaver running. For now, I can reproduce this with the "pop art squares" screensaver (but may work with others);
2) Ensure the screensaver never started before in the current session;
3) Close the notebook's lid;
4) Wait the idle time when it should start;
5) Notice how, after that, Xorg has crashed and lightdm login screen appears, showing the user is not logged in.

This does not work 100% of the times. By the log messages, it may be related to the disabling of the screen when the lid is closed and xfce4-screensaver starting on what would be no screen, but then it crashes the session.

The steps that caused the crash are particularly noticeable on the xsession-errors log (it was attached with a few other relevant logs).

Relevant information:

Could be related to my "worst log" in bug 14782?
