bcfg2-web: exception when no 'statistics' section is found

mod_wsgi (pid=22438): Exception occurred processing WSGI script '/usr/share/bcfg2/reports.wsgi'.

 NoSectionError: No section: 'statistics'

I expected some more user-friendly message instead of 500 Internal Server Error when bcfg2 is not configured.

The exception is also thrown when web server process don't have access to read /etc/bcfg2.conf (which is the default situation).
