I installed inkscape 0.45pre2 using the Windows installer. Some of the effects don't work.

Most useful to me would be the "export/groups to pngs" script. If I run it I get an error message (see below). Does anybody have an idea how to get it working?

the error message is:

Traceback (most recent call last):
