Application: dolphin (4.13.3)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-39-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
The application crashed when the copy was ended. The copy was correctly executed (no corrupted files, anything), but Dolphin crashed.

Three Dolphin tabs where opened (the source directory (SFTP), the destination one, and a third unrelated one), if that matters.

Possible duplicates by query: bug 309277.

Reproducible: Sometimes

Steps to Reproduce:
1. Copy a bunch of files from a SFTP server to the local disk
2. Wait
3. When the copy is finished, Dolphin crash (sometimes, occured one time on my side).

Actual Results:  
Crash

Expected Results:  
No crash

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