Application: dolphin (4.13.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-29-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: Had two Dolphin windows open in differnt directories. Copied four samll text files from one directory to another by dragging. Opened a terminal in both directories (shift-F4). Ran 'octive' program in both terminals. Closed octave in both terminals. Closed one Dolphin window by clicking on the 'x'.  Other Dolphin window crashed. Note the terminals were still open. This is the first time this has happened. I had copied files from one window to another with no problem. Having the terminals open is new. I will try to repeat later.

-- Backtrace:
