- PrerenderClickToPlay
- PrerenderNaClPluginDisabled
- PrerenderNaClPluginEnabled

Really?  I thought that patch just added some tests...

I am pretty sure the problem is with the builder.

For the record this was indeed my fault (one tiny line added to the product itself to support the tests, and I missed adding braces).  See bug 100550 for details and improvements to make it harder to hit this specific issue in the future.  Sorry for the trouble.
