These services form a core part of the OS insofar that they actually
monitor (asynchronously of course) things like batteries, networking
etc; they are not supposed to be activated, rather they are supposed to
be started as part of the boot sequence much like any other core part of
the OS.

System-bus activation is mostly only useful for privileged helpers; one
way I like to think about it is that it's an extremely nice replacement
for setuid root binaries.

Actually FYI that bug was introduced on HEAD (by one of your bugfixes
even!); 0.5.9 is (almost) fine - it will get fixed for 0.5.10.
