Tried to recompile again with debugging symbols and later without
debugging symbols, no more crash, seem that my build directory was
corrupted in some case.

Some notes:

1. Any problem to create the binaries into builddir/bin like kdelibs
does, it makes it easier to run applications because no additional path
to libdbus-qt4-1 is required. I would add the relating stuff to main
CMakeLists.txt

2. ping/pong is located in examples and in selftests/qdbusmarshall/ping
.. /qpong. Isn't this duplicated stuff ?

3. In snapshots of dbus-win3 I had prefixed the examples with 'q' to
make it clear that this are qt related. This may escpecially sense for
ping. If the qt-dbus builddir bin is in the system path it may be
overriden by the system ping tool. Any comments ?

4. Not all testcases are working, but this may depends on qt release. I
will see when I can update to qt 4.1.3
