Subject: memory problems in arts

I'm still trying to track down these arts problems but I just have no clue
what arts tries to do. Here's a valgrind log. As far as I can see:
soundserver.h:453
_pool = target._pool; // this line triggers "delete this;"
_cache = target._cache; // this writes to free'd memory
What's going on here? And are we in trouble now because this code is all
inlined? (ie. apps need to be recompiled in order to make use of any
possible fix)
This is the same type of error I've seen elsewhere in KDE due to arts as well.
It's rather critical.
