[GeoNode-users] Permission denied when save thumbnail

[//./\\-/_.\\]

 Hello,
(with GeoNode 2.4 on Ubuntu apt-get install)
I receive a Internal Server Error exception while trying to update metadata 
for layers: http://<hostname>/layers/<layername>/metadata
Apache returns this: 
Internal Server Error: /layers/geonode:<layer>/metadata...File 
"/usr/local/lib/python2.7/dist-packages/geonode/base/models.py", line 564, in 
save_thumbnail    with open(os.path.join(upload_path, filename), 'wb') as 
f:IOError: [Errno 13] Permission denied: 
u'/var/www/geonode/uploaded/thumbs/layer-43fc3f6c-08b3-42a8-af0f-2b1e20821023-thumb.png'...
It appears to be a permission problem with thumbnail files. www-data is not 
the owner.Owner is the current user. Have I missed something when installing 
GeoNode?
