Description of problem:
xmms writes ~/.xmms/config in a not-so-safe-way.
when xmms crashes or system blows up while xmms is writing config file,
on next xmms startup you are probably left with empty/invalid config file.

playlist seems to be written badly, too, but that's another issue...
in case someone cares.
