Application: dolphin (15.08.0)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-7-generic x86_64
Distribution: Ubuntu Wily Werewolf (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
During copy of a bunch of folders from a USB mass storage device to another [e.g. pendrives, external hardrives, ...].

- Unusual behavior I noticed:
Selecting 'Write into' and 'Overwrite' works, the copy starts, the progress bar, and right when you think it will work, it crashes, interrupting the copy.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
