I try to publish multiple existing mercurial repository-locations though XAMPP Apache via CGI Python script hgwebdir.cgi ... as in this tutorial http://mercurial.selenic.com/wiki/HgWebDirStepByStep

I get the following error from the apache error logs, when I try to access the repository path with a browser:

Premature end of script headers: hgwebdir.cgi

[Tue Apr 20 16:00:50 2010] [error] [client 91.67.44.216] Premature end of script headers: hgwebdir.cgi
[Tue Apr 20 16:00:50 2010] [error] [client 91.67.44.216]   File "C:/hostdir/xampp/cgi-bin/hg/hgwebdir.cgi", line 39\r

[Tue Apr 20 16:00:50 2010] [error] [client 91.67.44.216]             ^\r
[Tue Apr 20 16:00:50 2010] [error] [client 91.67.44.216] SyntaxError: invalid syntax\r

This is the path of the file where the script fails (and if I remove it, I get an empty HTML page shown with no visual elements in it):

[paths]
test = c:/hostdir/mercurial/test/
/hg = c:/hostdir/mercurial/**
/ = c:/hostdir/mercurial/

Does anybody have a clue for me?
