[Kde-pim] Fixing D-Bus interfaces as we go

[Samat K Jain]

You've actually found a problem that I found with kde-pim and several other KDE applications (e.g Marble) a month ago. I've been sitting on reporting bugs.

AFAIK, DBus doesn't specify one way or another whether method overloading is allowed. It's put upon the language bindings (e.g. python-dbus) or utility programs (e.g. qdbus, dbus) on how to handle it. This is why dbus-send works, but qdbus doesn't. This is remarkably bad omission on the part of the standard.

There's some discussion on the topic of overloading with a bug I filed on f.d.o against python-dbus:

Ideally, I'd just change the names of all overloaded methods (I was intending on filing patches to do this). My concern is that this would break existing applications depend on the overloaded methods, which may exist if they use DBus bindings that support overloading (for example, any C++ Qt app).
