Disk Used Space on Dashboard

Hello,

First, thanks for this project!
I’m try your cms in virtual machine (Vmware Workstation 12)
I have installed Ubuntu Server 16.04 x64 with 2GB RAM, 1 cpu with 2 core and 100GB vmdk

[3795:3663 0:39] 10:11:25 Sat May 27 [root@QuickBox] ~

# /etc/fstab: static file system information.

# that works even if disks are added and removed. See fstab(5).

UUID=b879ac81-40ca-4122-aa7c-ecf8d28bb0e7 /               ext4    usrjquota=aquota.user,jqfmt=vfsv1,errors=remount-ro 0       1

I have used setdisk for my user (20GB)
Quota mount on "/"
For the test, I transferred a 200MB file with WinSCP in /home/username/torrent
I tried “fix-disk_widget_root” and reboot virtual machine but it’s same issue

With showspace, the used space it is good

The Used space in dashboard dont update
