           Summary: window close widget causes resource exhaustion - 99% CPU
                    and slow memory leak
           Product: konsole
           Version: 1.3
          Platform: Debian stable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel at kde.org
        ReportedBy: james at grayonline.id.au


Version:           1.3 (using KDE KDE 3.2.0)
Installed from:    Debian stable Packages
OS:          Linux

Here's the sequence, can anyone confirm?
1. Start a new session (ie, log in from KDM)
2. Load "konsole"
3. Close console using the "X" in the title bar.
   I now have "kdeinit: kwin" and "kdeinit: kded" hammering the X server
   100%.  3 processes all vying for the same CPU so system load hit's 3+
   and memory starts disappearing steadily.

However, if I repeat #1 and #2 but this time use the menu "Session -> Close Session" or using "CTRL+D" instead of using the "X" widget in the title bar, everything works as expected - *NO* CPU hog and no memory leak.  I have a stack trace after using the close widget if that's useful?  Tried a backtrace using "gdb konsole" but it reports that konsole exited normally.

System is a Dell CPx-J laptop with ATi Rage Mobility M1 chipset, P3-650 and 256Mb RAM running a 2.4.24 kernel (patched to provide mppe/pptp support) and running standard Debian repositories plus the "backports.org" back-ports.
