Hello John,
I don't like the debugging code in Dbus-C++. I took it over from the
former maintainer. I have the long time plan to replace it with
log4cxx when I've time -> what will never happen. :-P
If you raise your arm to provide a patch to replace complete logging
system with log4cxx than welcome :-)
