Bug 348828

Application: konsole (15.04.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-18-generic i686
Distribution: Ubuntu 15.04

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

closing a remote ssh session, then Ctrl-D to exit console.

- Can always be reproduced as follows:

1) open konsole
2) press enter once 
3) exit console by either pressing Ctrl-D or entering the "exit" command.

Crash does not happen when you leave out step 2.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
