Christoph,

So basically what's going on here is that GCC is probably being a little
too helpful in this case.  It's complaining that it's going to call a
method with an uninitialized variable, but the only reason we need the
variable is to figure out which overloaded method is called, which means
that the variable is never actually used.  It does it this way to exploit
the recursive call in order to build up the proper D-Bus signature -
although now that I think about it, it may be possible to use TMP to
achieve the same effect...(I will look into it sometime this week/weekend.
 I'm currently updating the dbus-cxx tools)
