Silva 1.1b1: RenderError when using XSLT renderer

Hello developers,

I downloaded the new Silva 1.1b1 installer and tried it. At first, the 
XSLT renderers did not show up, so i downloaded and installed the 
libxml2/libxslt libraries (libxml2-python-2.6.11.win32-py2.3.exe).
While installing the libraries, the installer wasn't able to detect 
Silva's Python 2.3, so i had to install Python manually.

Launched the ZMI, and the XSLT-renderers showed up. However, viewing any 
content resulted in the following error:

Traceback (innermost last):
