Here are the 6 files containing debug output from the wikipublisher server. I got the error and saved off the debug as bad-full.txt and then I removed a single page from my trail and saved off the debug as good-full.txt. Then I edited each of those and saved off bad.xml and bad.latex as well as corresponding files with good.

I hope somebody can point me to what I'm doing wrong...
