Application: dolphin (15.08.3)

Qt Version: 5.5.1
Operating System: Linux 4.5.0-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
Trying to copy a 1.1GB file to an sftp:// location (KIO connection in Dolphin) and the crash happened.  In the meantime, that Dolphin's Terminal was performing a tar operation.

The crash can be reproduced sometimes.

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