           Summary: Konsole crashes after some output. If started again,
                    might crash even faster.
           Product: konsole
           Version: 1.6.4
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel kde org
        ReportedBy: arto.viitanen pp4 inet fi


Version:           1.6.4 (using KDE 3.5.3 Level "a" , SUSE 10.1.1)
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release 2.6.16.20-2-smp

Konsole crashes after some output, for example ls on home directory a couple
of times. My OS is SuSE 10.2 Alpha 2. On Alpha 1, there was no problem. When
I asked this on opensuse maillist, they told that Alpha 2 is compiled using
more intelligent memory management library.
 
Therefore I run the program with kde-debug-info and kdebase-debug-info of SuSE
10.2 Alpha 2 under valgrind. I don't like to put the log file here, since it
is too long, but here is the summary:
