Basically this seems to be an issue at compile time: kde4_add_plugin 
doesn't seem to add the CMAKE_CXX_FLAGS correctly: there should be a 
-DQT_NO_DEBUG/-DQT_DEBUG flag in there, it helps to add it though - so 
basically we should either change the macro to correctly include that, 
or we add that in the phonon cmakelists.txt file.
