Version:           1.1.80 (using 4.1.68 (KDE 4.1.68 (KDE 4.2 >= 20081001)), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.26-gentoo-r1

What  I did:

- I had two dolphin windows running (first split mode, working on an external USB HDD and a local folder)
- In the second window I (double) clicked on the icon to access the external HDD.

After some seconds, dolphin crashed with the backtrace below. As the backtrace looks to me as if it was more related to selection and copy and paste: I did indeed select some files to be cut in the first dolphin window. (as the computer was under heavy load, these actions took some second, so I was working on the second instance in the meantime)

Application: Dolphin (dolphin), signal SIGSEGV
