Bug Description

I've just installed dashboard on a Ubuntu 12.04 B1 server:
openstack-dashboard 2012.1~rc1~20120315.1545-0ubuntu1

# apt-get install openstack-dashboard

and just pointed my browser to the installation.
On logging on I get a stack trace.

Exception Type: OSError at /syspanel/
Exception Value: [Errno 13] Permission denied: '/var/www/.novaclient'

/var/www is quite rightly owned by root:root on an out of the box install of Apache.

This should fix the issue https://review.openstack.org/5608

The linked commit does enable gracefully handling permission errors when writing a cache file in the caching directory, but this bug apparers to be an issue when novaclient attempts to create the directory (prior to writing the file), perhaps the try/except block of the original fix be expanded to also catch errors during creation of cache_dir

Thanks Thierry. Is this something we should expect to trickle into milestone-proposed, or should we prepare to carry a patch?
