SUMMARY
Using System Settings to auto-mount an internal NTFS partition causes the "Sleep", "Restart", and "Shut Down" buttons to disappear from the Application Launcher. The buttons will be missing after a reboot, but they will come back after logging out and back in again. Rebooting will cause them to disappear again.

This behavior was observed on a system that has a secondary SSD containing a Windows installation. The steps to reproduce include exactly how I'm mounting the partition.

STEPS TO REPRODUCE
1. Add the current user to the "storage" group: `sudo gpasswd -a $USER storage`
2. Create a polkit rule to allow your user to mount the partition.
Path: /etc/polkit-1/rules.d/allow-mount-internal.rules
```
polkit.addRule(function(action, subject) {
    try {
        if (action.id == "org.freedesktop.udisks2.filesystem-mount-system"
            && subject.isInGroup("storage")
            && subject.local
            && subject.active)
        {
            return polkit.Result.YES;
        }
    } catch (e) {
        // Don't break polkit
    }
});
```
3. Navigate to System Settings > Disks & Cameras > Device Auto-Mount. Under Attached Devices > Basic data partition, check the box for "On Login" and Apply the settings.
4. Reboot and log in.

OBSERVED RESULT
The "Sleep", "Restart", and "Shut Down" buttons are missing from the Application Launcher.

EXPECTED RESULT
The "Sleep", "Restart", and "Shut Down" buttons are present in the Application Launcher.
