Dear Maintainer,

Recently tracker-store and rygel processes started using up all the IO after
logging into KDE for the first few minutes. This is really annoying, because
everything else is IO starved and starts super slow.

iotop usually looks like this:
grzes:/home/ga# iotop -boP

I think I found out why this issue emerged right now, there seems to be a
bug in the KDE settings system, where it automatically turns on the file
indexing, even though the option is unticked in the dialog box. So
basically there are two issues from my perspective:

1) It is not possible to switch indexing off. You can switch it off for the
current session, but it will be enabled again after restart.
2) Indexing is so slow, that it is absolutely not usable. It freezes the
whole system.

Kind regards,
Grzegorz

The file indexing in KDE settings controls nepomuk/strigi afaik, *not*
tracker.
