debian/watch file and berlios

[Andreas Bresser <bresser@informatik.uni-bremen.de>]

Hello,

The upstream-author of my package "spe" uploaded a new release on
berlios.de (on sourceforge is still the old version), so I changed the
debian/watch-file from sf.net to berlios:
version=3
opts=downloadurlmangle=s/prdownload/download/ \
    http://developer.berlios.de/project/showfiles.php?group_id=4161 \
    http://prdownload.berlios.de/python/SPE-(.*)-wx.*\.tar\.gz

but this does not work:

~/debian/spe2/spe-0.8.2a+repack$ uscan
spe: Newer version (0.8.3.c) available on remote site:
  http://download.berlios.de/python/SPE-0.8.3.c-wx2.6.1.0.tar.gz
  (local version is 0.8.2a+repack)
uscan warning: In directory ., downloading
  http://download.berlios.de/python/SPE-0.8.3.c-wx2.6.1.0.tar.gz failed:
403 Forbidden

when I try to download this file directly with "wget" it works:
~$ wget http://download.berlios.de/python/SPE-0.8.3.c-wx2.6.1.0.tar.gz
--17:21:21-- 
http://download.berlios.de/python/SPE-0.8.3.c-wx2.6.1.0.tar.gz
           => `SPE-0.8.3.c-wx2.6.1.0.tar.gz'

so, does anyone know how to create a working debian/watch file for berlios?
