Application: dolphin (2.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-32-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
I was attempting to backup my music folder to an external hard drive, the folder consists of a large number of folders (108 at the top level) with ~ 20 gigs of data, mostly mp3 files. I attempted to do a drag and drop copy of all data using split screen mode. The crash occurred after the drag and selecting "copy" from the context menu. A second attempt copied correctly however (not immediately reproducable).

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
