            Bug ID: 364285
           Summary: Konsole crashes when saving output from closing tab
           Product: konsole
           Version: 16.04.1
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: awilcox at wilcox-tech.com

Application: konsole (16.04.1)
 (Compiled from sources)
Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.7.0-rc1-ciall x86_64
Distribution (Platform): Gentoo Packages

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

I fat-fingered Ctrl+Shift+S as Ctrl+Shift+S and D.  The tab closed but the save
output dialogue still opened.  When I chose Save in the dialogue after typing a
name, this crash occurred.

The crash can be reproduced every time.

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