New crash information added by DrKonqi

konsole (2.14.2) on KDE Platform 4.14.14 using Qt 4.8.7

- What I was doing when the application crashed:

For some reason konsole started to crash at each launch. Before that, it worked ok for some time.

Problem is gone (at least, for some time) after restarting KDE.

Just reproduced on Ubuntu recently updated to 16.04:
