'System Monitor - Hard Disk' plasmoid shows free disk space which is different from the one shown in 'df'

Bug Description

Description: Ubuntu 8.10
kdeplasma-addons:
Installed: 4:4.2.0-0ubuntu1~intrepid1

The 'System Monitor - Hard Disk' plasmoid shows free disk space for each mounted volume to be approximately 5% bigger than what 'df' shows in a shell. This number (5%) seems to be consistent for all volumes.
Somebody in #kde has suggested, this might be due to the disk space reserved for root, which is not shown in 'df'.
It could also be that the multiplier for the conversion of Bytes into Gibibytes is wrong, being 1000 instead of 1024. (Unlikely, but hey...)

However, even if it is the reserved space for root, wouldn't it make sense to subtract this from the values displayed in the plasmoid as it is non-usable disk space (D3lphin shows the same values as 'df', so I assume this disk space in question not to be usable).

The problem becomes quite significant with larger volumes, causing a difference of 10 GiB in my case when 43.5 GiB of 202 GiB are free, for example.

I can confirm this. Dolphin says I have 10 GB free while the plasmoid suggests I have 12 free.

Oops, wrong bug. There is a patch committed upstream for this bug though. I'll look in to backporting it to our packages.

I've committed the patch to our packaging. The next packaging release in Kubuntu 9.04 will fix this.
