lilypond-book (lily2.8.2-1) fails on Win XP (SP2)

[Mike Hüllenkremer]

Dear developer team and friends of Lilpond,

yesterday i installed the most up to date precompiled lilypond version for Win 
(v2.8.2-1). I have no phython installed other than the one that was delivered 
by the lilypond-setup. 
To verify the installation i ran basic examples from the documentation. While 
there were no problems using lilypond, i got the following error message 
running lilypond-book on the example given in chapter 13.1 of the documentation:

C:\Programme\LilyPond\test>lilypond-book --output=out --psfonts book.ly

Traceback (most recent call last):
  File "C:\Programme\LilyPond\usr\bin\lilypond-book.py"
    import lilylib as ly
SystemError: NULL result without error in PyObject_Call

Can you please give me advice how to get lilypond-book running? Thank you in 
advance for your help.

Mike
