Application: konsole (15.08.0)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-25-generic x86_64
Distribution: Ubuntu Xenial Xerus (development branch)

-- Information about the crash:
- What I was doing when the application crashed: When closing Konsole (usually by pressing Ctrl+D) it often crashes randomly for no obvious reason. I can only recall it happening on Ubuntu 15.04, 15.10 and 16.04 which are based on QT5. Ubuntu 14.10 and earlier which are using QT4 seem perfectly stable in this regard. The same pattern has been visible on multiple machines with different hardware configurations but most of them have been using different models of NVIDIA cards like Quadro 600, 9600GT or GTX 970.

The crash can be reproduced sometimes.

-- Backtrace:
