VIP handling of Interlaced video

I have the V2 reference design, which includes new Beta versions of the following cores:

Clocked Video In

Clocked Video Out

Frame Buffer

Deinterlacer

Interlacer

All of them have various modifications to properly handle interlaced video. Unfortuntely, with Quartus 9.0 sp1, I cannot compile either the reference V2 design, or my own design. I bomb out with the following error (twice) when the VFB (Frame Buffer) is being elaborated:

Error: IP Generator Error: Variable msg_field_interlace_4 does not exist in the variable life table

At that point Quartus II gives up and we are done.

Unfortunately I don't think the regular frame buffer will work, as the beta one has a new checkbox for enabling "Interlaced video compatibility".
