Executá-lo a partir da linha de comando resultou em uma falha de segmentação:

$ emulator -avd nexus_s
Segmentation fault (core dumped)

No entanto, executando emulador-braço diretamente da seguinte maneira, funciona bem.

$ emulator-arm -avd nexus_s

Eu suspeito que ele está tentando executar os mips ou x86 versão do emulador. Existe uma maneira de configurar o emulador que executável para iniciar?

Tudo isso começou depois de atualizar para o Android SDK 17.

Adicionando o sinalizador -verbose dá a seguinte saída (que eu não acho que adiciona qualquer informação):
