Short review of two commits

[Michael Jansen]

Hi

I fixed a bug in amarok. Change is quite simple but i changed some methodnames 
and class members. Since i am not that firm in all things amarok could someone 
please review if the commit

121f91675dbf68072cefe486ccdabfff922cc0d5 and the one before that.

is bc and source compatible? Does Amarok have such promises? Perhaps i am just 
to kdelibs style sensible.

Mike
