Oke, seems i was mixing things up quite massively. I completely mis-read the
bug report (i blame my ipad :p) The reporter was right and i was wrong.

KImageCache is indeed not used for thumbnails. Rather it's used for icon
caching.

But this did left me wondering: "Where are those thumbnails being generated at
the moment?" Since dolphin isn't doing that on it's own:
http://quickgit.kde.org/?p=kde-baseapps.git&a=blob&h=eaaab6bc0529f1f72a2bc81ea3b1cd3729f8280b&hb=cab86c292b530ae52c504124e9c77af96cef7f01&f=dolphin%2Fsrc%2Fkitemviews%2Fkfileitemmodelrolesupdater.cpp
the only caching it seems to rely upon is the PreviewJob cache.

So upon further investigation in PreviewJob it quickly became clear to me that
PreviewJob is managing this. Only not in the .cache folder.

So my earlier statement that KIO is not the place to decide this is false since
PreviewJob is doing this.
Also for my own question where this should be done.. PreiewJob apparently ;)

To conclude:
Currently: ~/.thumbnails is used
Needs to be: ~/.cache/thumbnails

Obviously changing bug report from wontfix to verified and remind. I will take
care of this issue now. I have the tendency to forget bug reports so if you
don't see progress within ~2 weeks, please do remind me! :)

It seems as simple as changing:
    d->thumbRoot = QDir::homePath() + QLatin1String("/.thumbnails/");
to:
    d->thumbRoot = QDir::homePath() + QLatin1String("/.cache/thumbnails/");

Yet another thing i mixed up :( i meant IZ indeed. I hope the interest gets
back in that project since it seems very promising!
