I am not sure what is going on here. But I changed the internal event scheduling today. Could you please try again with the newest from branch 4.8 (or trunk). I might have just fixed that today.

Comment on attachment 70340 [details] New crash information added by DrKonqi I'm not sure why it's been added to this bug entry, but I wasn't adjusting the volume or interacting with KMix whenever it crashes.
