Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Linux Mint 17.3 Rosa

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

I deleted a file in dolphin and whe in confirmed the "delete" the system crashed

I don't know what "KDE Platform is compleid from sources" exaclty means and appreciate a short information on that.

All KDE components on my PC are installed from Linux Mint official repository.

The crash does not seem to be reproducible.

-- Backtrace:
