To reproduce, he does:
1. enable compositing for kwin (to do this, run "kcmshell kwinoptions" and
enable Tranparency and drop shadows there).
2. start yakuake (a quake-style terminal emulator for KDE).
3. in a yakuake terminal, start mplayer with some audio file.
4. Open a new tab in yakuake (Ctrl-Alt-N).
5. hide yakuake (by pressing F12).
Xorg now crashes.
