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

Steps to reproduce:

1) Open dolphin
2) Go to some folder
3) Go up one level (using the "up arrow" icon
4) rename the folder you just came from
5) See dolphin crash with the backtrace below:

Note: This also works with konqueror (KIO related?)

Application: Dolphin (dolphin), signal SIGSEGV
