gnome-session-manager accepts only one partition mount command

[Michael Rose]

On my dual OS machine (Ubuntu 14.04 and Windows 8.1), I want to automount two partitions at boot time. To that end, I followed the steps for Per-User Mounts on https://help.ubuntu.com/community/AutomaticallyMountPartitions. Adding one or two mount commands is no problem. However, after restart, only the first mount command is executed, while the other has disappeared.
