Nice to hear and thanks for your effort.

Today I discovered another preview problem with the Information Panel. I 
downloaded the Big Buck Bunny Movie from 
http://www.bigbuckbunny.org/http://www.bigbuckbunny.org/ and when I tried to 
open it, Dolphin freezes for almost a minute. I guess the Information Panel 
tries to read the whole file, because the memory usage from Dolphin went up to 
over 500MiB.

Btw, I use kde4 from trunk, so the problem is in the latest version.

Thanks,
Mathias
