I try to build PDF documentation from current Python-2.6rc2 and Python-
3.0rc1 versions. I tried the process under Windows XP and also Linux 
(Ubuntu). The results are the same. The documentation is not built 
correctly, mostly the table of contents and always the index is missing. 
pdflatex always stops with the same error:

! Too many }'s.
l.122 }

Line 122 refers to the file sphinx.sty.

After stopping, I rerun pdflatex with the command "R" to completion. 
This run has been created via the 3.0rc1 files, based on WindowsXP.

I will include a log file from the pdflatex build process. The error is 
in line 364 of file tutorial.log. 

The pdflatex (WindowsXP) version is:
MiKTeX-pdfTeX 2.7.3147 (1.40.9) (MiKTeX 2.7)
