Application that crashed: dolphin
Version of the application: 1.2.80
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I was moving a folder in column mode to one of the folers in the path above the column view (the path was like /home/gshyde/media/singles and the columns were the folders below singles). It crashed when I tried to move a folder from a couple levels down in the column view into the singles folder from above
