Update: I just checked how Dolphin for KDE 4.0 behaves in this regard. There I 
just pass the URLs of the items to the PreviewJob and before the job is 
started, Dolphin gets blocked too for a few seconds...

I'll do some profiling if I have more time again, I hope I can find a solution 
for KDE 4.1.

BTW: can you confirm in your environment that when going into a folder with e. 
g. 1000 images that no blocking of the GUI occurs?

Thanks!
Peter
