I did run Compiz at the time. However, bug 21132 indicates that crashes occur
rather frequently, but this has only happened once to me after upgrading to
Ubuntu Jaunty (I upgraded when it was late in beta phase). So I reported it,
but unfortunately I have no idea how to reproduce it.

The only "hint" I got is that I remember changing font rendering options back
and forth some time before the crash (from sub-pixel to gray-scale and back a
few times). Also, sub-pixel font rendering tends to result in corruption for
some glyphs, which indicates a problem (might just be related to other small
pixmap corruptions that happens with the radeon driver and my graphics card,
like bug 18397). I'll try and see if I can provoke crash by jiggling with font
settings.
