Application: dolphin (2.1.85)
KDE Platform Version: 4.9.90
Qt Version: 4.8.3
Operating System: Linux 3.5.0-19-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
When select file and folder that has subfolder at the same time and then copy and paste them to 
any folder , Dolphin crashes. Dolphin didn't crash if the folder did not have subfolder. 

Here is a step-by-step guide for reproducing problem:
1. Open terminal and execute these commands: 
mkdir to
mkdir -p what/in
touch text

Step one can be done in graphical way too

2. Now open Dolphin, and go to directory where you created text:
First select "text"-file and then select "what"-directory an. Now open "to"-folder and paste. At this point Dolphin crashes.

Sometimes I have to delete everything inside "to"-folder and then paste again. 

Dolphin doesn't crash if I right click "to"-folder and then select paste option. I can do that as many times I want and it doesn't crash. Only when I open "to"-folder.

Folder and / or filenames seem to matter too. If you replace name 
"to" with "a",
 "what" with "b",
 "in" with "c" and
"text" with "f"

Then dolphin won't crash. It doesn't matter if you rename folders or create folders with those names.
