Application: dolphin (14.12.3)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:

Renaming a file .srt (subtitles) using Dolphin (clicking right mouse button).  This problem only occurs with this file.  The file is not broken and it works by watching the video. 

Solution: I was able to rename the file using the command mv in terminal.

The crash can be reproduced sometimes.

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