Mike,

Here’s the tail I’m getting; it’s the only line that appears:

127.0.0.1 – – [24/Nov/2010:10:17:03 +0000] “GET /?feed=rss2 HTTP/1.1” 200 446 “http://aaaaa.bbb?feed=rss2” “SimplePie/1.3-dev (Feed Parser; http://simplepie.org; Allow like Gecko) Build/20101123102807″

Incidentally, I tried switching themes to the default and deactivating all plugins and got the same blank pdf.
