Crashes on wma

[dezza]

I was wondering why Exaile crashed, so I started it via xterm to quickly see the problem.

** Message: don't know how to handle audio/x-wma, wmaversion=(int)2, bitrate=(int)128016, depth=(int)16, rate=(int)44100, channels=(int)2, block_align=(int)5945, codec_data=(buffer)008800000f00e55c0000

This was the last line on xterm when it crashed. I don't ever listen to the few wma files I haven't converted yet, so I would appreciate if this is just ignored if I do not have any wma-codecs installed.
