Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-34-generic x86_64
Distribution: Ubuntu 14.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was copying a 500GB (465GiB) HDD image file from one portable HDD to another. I was using the KDE indicator for status of copying files. I wasn't doing anything else as a user, and left it overnight, so not exactly sure what happened just before it crashed.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
