Same problem for me. I'm using yakuake on gutsy (in gnome), on an athlon 1800+ (ia32) with an nVidia geForce3. I'm not sure if the same problem was there in feisty, because I didn't start using compiz-fusion regularly until gutsy. I've been reproducing it reliably (usually takes a few seconds) by running a couple cpu-intensive mencoder processes in yakuake, then doing *anything* else in any other application. Took me a long time to realize yakuake was the culprit, because it's the only terminal I use these days, and less resource-intensive processes (even firefox) didn't cause x to crash.
