Hello. 
Are you still able to reproduce this bug?
I've tried with 5000 subfolders, with dolphin from 20121027, and I'm not able to reproduce it.

Does it happens when you just enter the directory, when you select some directories, when removing some of them? when preview enabled/disabled?.

Trying to reproduce dolphin bugs:

Comment 2 Simon Andric 2012-11-01 12:27:42 UTC 
hello!

First let me appologize for late reply but for the past weeek my computer was in service, my ac adapter burned so until now i didnt had opportunity to test dolphin. Now, for the past 2, 3 days howwever i did and i must say that with the latest update of dolphin the crash (until now) didnt happen again. with saying that i didnt use dolphin as much as before yet so i might post here again *if* the crashes start to happen again.

and to answer your question: it happened when i tried to enter the directory, i clicked on the directory, and as soon as one would expect to see a list of folders/files in it, dolphin crashed.

same thing also happened if i wanted to paste some other files/directories with various persmission attributes somewhere (no matter where exactly).

hope it helps

nice day!

Symon :)
