            Bug ID: 342227
           Summary: Konsole crashes when quiting program running in a tab,
                    typing exit
           Product: konsole
           Version: 2.13.2
          Platform: Kubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: tabbar
          Assignee: konsole-devel at kde.org
          Reporter: twtroughton at gmail.com

Application: konsole (2.13.2)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-43-generic i686
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: I restored konsole with 3
tabs, saved and closed emacs, closed wyrd, Konsole crashed. 2nd time it
happens.

- Unusual behavior I noticed: I was playing Kerbal Space Program, the machine
was pushed into swap, rendering of window titles and menus degraded, many video
artifacts, especially firefox - could not render my zotero library properly.
Closed firefox, then went to close Konsole. Still degraded, a logout is now
required to restore the rendering of window titles and menus.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

Report to https://bugs.kde.org/

Reproducible: Sometimes

Steps to Reproduce:
1. Drive system into swap with Kerbal SPace Program.
2. Have open some tabs, load up programs (bash prompt, wyrd, emacs with open
org file)
3. Save and close emacs, type exit, switch tab with mouse 'Q' to close wyrd,
type exit.
4. Crash

Actual Results:  
Sometimes it crashes. As I said in my report, the video was having problems,
and the windows and menus of KDE were not rendering correctly.

Expected Results:  
Konsole should exit cleanly.
