+Hugo, I didn't write this code, but it looks to me like you could work around the problem by changing line 207 of lib/CommonFunctions.py:

+<pre>
+diff --git a/lib/CommonFunctions.py b/lib/CommonFunctions.py
+index 050b93e..083f5d6 100644

+         if get(\"progress\"):
+             data = False
+             tdata = \"\"
+-            totalsize = int(con.headers['content-length'])

+Probably the API used to return a content-length header, and no longer does, or doesn't do so reliably. It does not seem to be used for anything too important -- this change will break git-annex's progress display a little bit, perhaps.
