           Summary: Konsole does not kill su root 'top' process which
                    zombifies
           Product: konsole
           Version: 1.6.5
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel kde org
        ReportedBy: jesnow uh edu


Version:           1.6.5 (using KDE KDE 3.5.5)
Installed from:    Gentoo Packages
Compiler:          sys-devel/gcc-4.1.1-r3 
OS:                Linux

If I run top as root in a konsole window, then click the window away without 'q'-ing or ctrl-c'ing out of top, then the top process goes zombie and claims 100% of cpu. 

I have reproduced this on 2 different machines. 

Here is the output of a second 'top' (not run as root):
