Got this (for user@1000.service) on new installs of Lubuntu 14.10 64-bit on one machine, and Ubuntu Server 14.10 32-bit on another. On the Lubuntu machine, I had other issues with the on-motherboard video, so I put another video board in it and re-installed Lubuntu, and this time this bug did not come up. I'm not sure why using different video worked fixed (or worked around) it, but perhaps it might provide a clue of what's going on?
