Changing frame duration increases image size

Whenever I change the duration of a frame in an animation it increases the size of the image for that frame to a size that causes Java to run out of memory if I try to view it in Pencyl. I think it might have to do with Scale settings I have messed with but I'm still not sure why it doesn't trigger till after I change the frame duration.

Which build are you using?

The most recent one, 8529.

Oh, sorry, I thought the fix for this was already public. It should be fixed by now, and there will probably be a new public version soon.
