           Summary: KDE Konsole crashes, no direct user actions was
                    involved.
           Product: konsole
           Version: 2.4.3
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: janbku at gmail.com


Application: konsole (2.4.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 3"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.5-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
A simple program with moderate text output was started from the konsole.
After approx. two days of operation the KDE Konsoled crashed during a long
period with no user activity - the screen was locked.
The scrolling was fixed at 99999 lines.
The system is equipped with 4GB ram & 8 GB swap - OOM shouldn't be a issue.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Konsole (kdeinit4), signal: Segmentation fault
