[KDE/Mac] More audio strangeness

Hey all,

I thought I'd look a bit further into debugging why audio isn't working in
kanagram which uses QtMultimedia via qml to play a chalk sound for each new
word. I added some debug lines to the qml and found that the MediPlayer is
getting ServiceMissing error when it's trying to load the media service. I
also seem to be somehow getting both the _debug.dylib and the .dylib qt
libraries loaded somehow as shown here. any idea why that would be? Did I
mistakenly build in non debug mode once (creating the multimedia plugin)
then again in debug mode or something when building my qt5build build of qt
dev branch with the qsp patch?
