Windows XP, convert-ly in versions > 2.8.1

[Thomas Scharkowski]

Python problems under Windows have been reported before.
The last LilyPond version I could use convert-ly is 2.8.1, with 
Python 2.4.2 supplied by LilyPond  and Python 2.4.3, separatly 
installed.  

With 2.8.2 or 2.9.5 (and any other version after 2.8.1) I ger error 
messages:
