Extension manager / unopkg not working in 2.2.0

[Alex Thurgood]

Hi all,
I'm trying to install extensions into OOo from the OOoWiki extension 
repository, but they keep failing with the following error message :

./unopkg add '/home/alex/Desktop/oooblogger.zip'

ERROR: Erreur lors de l'ajout : file:///usr/home/alex/Desktop/oooblogger.zip
       Cause: bad tranfer url

unopkg failed.

Java 1.5 Diablo JDK is installed and recognized by OOo.

What's up ?

Alex
