Bug 351778

Application: konsole (3.0.1)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
I just pressed to "Close"  and Konsole is crashed. It crashing all times when I am trying to reproduce bug, whatever with question "There are opened applications (for example - mc or htop), do you want to close them?" or without. It is no dependent from launched soft and it can be replicated of other PCs w/ Kubuntu 15.04 (did not tried other distros).

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
