Steps to Reproduce:
1. Remove output plugin from ~/.xmms/config, start artsd
2. Start xmms; it detects artsd and defaults to the arts output plugin
3. Hit play
Program received signal SIGSEGV, Segmentation fault.

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.
Having it link directly to libartsc instead of dlopen()ing it doesn't help.
It looks like there's problem with library unloading in conjuction with
X11. I have added a workaround in xmms, so it should work now.
