This is Bas's fix.

Bas, you might want to regenerate the patch with genshaders to minimize the bytecode churn.

My compiler wasn't much better. I wonder who last generated :-). Anyway.

I know this is closed, but should this have been a blocker?  I'm *watching* for people working on non-blockers, and this showed up on my radar.  If it should be blocking, please make the call.  If not, we need to stay focused on blockers!!!

Yes this probably should have been a blocker.

The reason this wasn't labeled a blocker was because when Roc found it he asked me and I knew right away what to do so we created the bug with the patch right away. I then asked joe for approval the patch rather than specifically asking him to make this a blocker and land it then, my mistake. But yes, this would've certainly been a significant bug.
