Description of problem:

arts segfaults when opened to play a song if it's been opened to check if it's
available before.

3. Hit play
    
Actual results:

This doesn't happen when playing normally (i.e., when not using the detection code.)

What the detection code does is:

- dlopen libartsc.so.0
- run arts_init(), check the result
- run arts_free()

I'm pretty sure this used to work at one point.
