b6 & b7 Crash when drawing curve in clip view

[Chris J]

I was in beta 7 : I had a 2 bar loop & an impulse with 2 sounds running, I was drawing a curve on the loop, assigned to an auto-filter, but then reproduced with the curve assigned to sample offset,
It started by cutting off the audio of both tracks altogether. Then after a while the audio came back but the loop played twice and then stopped, I got a weird sound and a serious error.

I went back to beta6, and the same thing happened.
(crash log was sent)
