------- Additional Comments From M.B.Lankhorst@gmail.com 2007-27-06 15:23 ------- If you can figure out why the assertion fails you'll have your music back.
What I recall from the first patch is that there were a lot of circular dependencies so I had to cut down on them, my guess is that the patch I wrote exposed some deeper things wrong.
Second patch has nothing to do with what's wrong.
All you're missing is the thread.
try a +quartz with and without the first patch and see what's different.
