Application: plasma-desktop (4.11.14)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 3.19.0-49-generic x86_64
Distribution: Ubuntu 14.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed: I have two icons on the desktop that are shortcuts to start applications. I wanted to rename one of them. When I finished renaming it, the system started to update and then kwin crashed and the icon disappeared and did not return.

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