I am able to reproduce this by opening an xterm in the floating area,
running "sleep 3; exit" command in the xterm, then grabbing it and
moving it around. After 3 seconds, the xterm body disappears, leaving
behind the window manager decorations and a solid window body.

This zombie client remains in the floating area. If I right click its
title bar and choose "kill", nothing happens. If I choose "slay", wmii
crashes (core dumped) just as Tom described.

You should file this as a bug on the wmii issues tracker:

Yeah, it's uncommon, but nothing to worry about. Just ignore it. :-)
