Do you get something on the console/stdout if you start xfce4-power-manager on the console? If that happens only sometimes: Maybe is it after you change something at runtime, maybe changeing a battery or so? =2D-=20 You are not supposed to start Emacs more than once in a lifetime, so the startup time shouldn't matter at all.
