Ouch, I got bit by the blank home page again. My client called me on it, and was not at all happy

Clearing the cache immediately resolved it.
The site is 2.0.4-pl. I upgraded to 2.0.7-pl in the hopes that a fix was included in the package, but it looks like it’s an open issue.
I copied the cache before clearing it. Here’s a snip of the contents of [tt]1.cache.php[/tt], where you can see that nothing *appears* out of the ordinary. I have the entire cache directory available; I can send that to devs for analysis if it might be useful:
