Version:            (using KDE KDE 3.3.0)
Installed from:    Unlisted Binary Package
Compiler:          gcc 3.3.4 
OS:                Linux

I'm currently running PLD Linux 2.6.9rc2 kernel, glibc 2.3.4 (nptl version), KDE 3.3, Openoffice.org 1.1.2, Xorg 6.8.1 (with patches from ximians ooo-build).

The problem is when I open few OOo documents (ech OOo window is taking whole 1024x768 screen) and then switching with alt+tab few times causes kwin to abort with SIGABRT (unfortunately binaries are stripped so no usable backtrace)

kwin: Activation: Belongs to active application
kwin: h:426:t:19:b:4
kwin: kwin/geometry.cpp:1643: void KWinInternal::Client::plainResize(int, int, KWinInternal::ForceGeometry_t): Warunek zapewnienia `false' nie został spełniony.KCrash: Application 'kwin' crashing...

Problem happened for me with various glibc, XFree86 (now with Xorg), kde versions for quite some time but I wasn't frequent OOo user then.
