            Bug ID: 338997
           Summary: Konsole crashed while I was selecting text, causing
                    the window to scroll up
           Product: konsole
           Version: 2.13.2
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: copy-paste
          Assignee: konsole-devel at kde.org
          Reporter: a1291762 at gmail.com

Application: konsole (2.13.2)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-35-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

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

Selecting a bunch of text (which I was going to paste into a file). Causing the
window to scroll up. Scrollback is capped at 10,000 lines. The tab I was in
probably wouldn't have hit that though as it was newly-opened.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
