Dock disappears after a few minutes inactivity

[bastienho]

Since a while, I got a strange behavior, after about 20 minutes of inactivity, without sleep or screen lock, the dock disappears.
Even the alt+tab trigger do not shows anything.

alt+F2 + r fails and asks me to restart the session.

This time, before restarting, I looked in syslog and found this:
