Application: dolphin (4.13.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
I used three Dolphin windows to separate about  700 music files into two directories. I played / skipped through the file with the preview player of the source window, and dragged them over into one of the destination Dolphin windows, separate or in small groups.

The crash occurred when closing one of the target windows. I think I clicked the close icon in the window decoration header of the first, which caused it, and the second, to close as part of the crash.

The source window, which I had opened first,is still open while I write.

I opened Dolphin specifically for this task, so the process was not used for much else before (except for navigating to the directories).

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