Urgh. Never code when sleep deprived. Sorry about that. Anyway, I've
already been sent patches about the GError and the memory leak, but
the path thing still needs fixing. I'm not sure setting a process PATH
is such a good idea --can't we just pass this in as envp? Or maybe we
need to just hardcode /usr/sbin?
