problema resolvido. O cache de fontes foi corrompido quando atualizei do Leopard para o Snow Leopard. Corri o seguinte no terminal, reiniciei, tudo está bem!

Eu tenho a versão mais recente do Snow Leopard com o Flash atualizado (r32, se bem me lembro).
O Safari é executado corretamente, mas as versões mais recentes para download do Firefox, Opera e Flock caem aleatoriamente e com muita frequência.
A seguir, uma mensagem de erro do Opera 10 (o despejo de memória e o despejo de pilha são removidos)
