            Bug ID: 358326
           Summary: Konsole crashes when pressing Ctrl+D (intermittent)
           Product: konsole
           Version: 15.08.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: johan.palmqvist at home.se

Application: konsole (15.08.0)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-25-generic x86_64
Distribution: Ubuntu Xenial Xerus (development branch)

-- Information about the crash:
- What I was doing when the application crashed: When closing Konsole (usually
by pressing Ctrl+D) it often crashes randomly for no obvious reason. I can only
recall it happening on Ubuntu 15.04, 15.10 and 16.04 which are based on QT5.
Ubuntu 14.10 and earlier which are using QT4 seem perfectly stable in this
regard. The same pattern has been visible on multiple machines with different
hardware configurations but most of them have been using different models of
NVIDIA cards like Quadro 600, 9600GT or GTX 970.

The crash can be reproduced sometimes.

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