Possible bug report

At BMD's suggestion, I removed the Sapphire lighting effects plugins from some of the clips that were crashing my renders consistently, and then ran into two clips that continued to crash consistently at the same spot.

One had no OFX plugins on it at all, one had a Sapphire effect that had rendered without a hitch earlier. Both were groups with group pre-clip grades on them. I copied the grades from the group, pre-clip section to the clips themselves and removed them from the group, they rendered through without a hitch.
