Terminator falha ao iniciar em i686, problema DBus em Python

Question

Eu tenho uma nova instalação do Arch em um sistema i686, executando o Terminator 1.91. O programa está se recusando a carregar, a depuração me dá a saída:

Parece que há algo errado é o DBus. Eu sou capaz de executar o Terminator usando

$ terminator -u

desdobrando o DBus; no entanto, se eu quiser configurar um atalho nas configurações do GNOME, ele não será aberto.
