XSLT Transformation in Dia for Windows

[Meik Wusterhausen gkss de]

The XSLT Transformationfilter (by "export" entry in menu) in "Dia for 
Windows" produces an empty(!)  "[...].code" file of the "[...].dia" 
document, also there is no other file made after choosing "UML" and "Java" 
or "Python" for example. Do I need to implement an external 
XSLT-Processor? In the Linux Version everything works just fine.
Thanks for your help and best regards!
