            Bug ID: 334803
           Summary: konsole crashes when closing tabs / separate windows
    Classification: Unclassified
           Product: konsole
           Version: 2.13
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: stephan.diestelhorst at gmail.com

Application: konsole (2.13)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

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

Closing one open window with Ctrl+D.

Not sure how I can check for my input method that I am using.  I have two
different keyboard layouts if that makes a difference?

ps aux|grep ibus shows:

/usr/bin/ibus-daemon --daemonize --xim
/usr/lib/ibus/ibus-dconf
/usr/lib/ibus/ibus-ui-gtk3
/usr/lib/ibus/ibus-x11 --kill-daemon
/usr/lib/ibus/ibus-engine-simple

ps aux|grep fcitx -> Nothing.

This has only started happening with Kubuntu 14.04, used to be on KDE 4.12 on
Kubuntu 13.10, and had no such issues.

The crash can be reproduced sometimes.
