           Summary: KSysGuard show incorrect Total Size for big (~2.7 Tb)
                    partition
           Product: ksysguard
           Version: 4.0
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: ksysguard
        AssignedTo: ksysguard-bugs@kde.org
        ReportedBy: amin@nm.ru


Version:           4.0 (using KDE 4.6.5) 
OS:                Linux

I had one big Ext4-partition (with size about 2.7 Tb) in GPT-labeled HDD.
I use [Partition usage] --> [Table (listview)] for watch the FS usage. The
[Used] and [Available] sizes show correctly (675.4 Gb, 1.9Tb), but total size
show incorrectly negative value -1 410 683 688 Kb instead 2.7 Tb.

The du command worked correctly:
[Amin@AminCave /]$ df -h | grep 3T
/dev/sda1             2,7T  676G  1,9T  26% /mnt/Hit_3Tb

Reproducible: Always

Steps to Reproduce:
1). Create one big Ext4 partition on "3Tb" HDD with GPT (ms-dos MBR can't
this).
2). Make mkfs.ext4 and mount it.
3). Watch total size in KSysGuard --> [Partition usage] --> [Table (listview)]
for big partition.

Actual Results:  
Total size = -1 410 683 688 Kb

Expected Results:  
Total size = 2.7 Tb
