The Trac process is unable to create a new folder due to lack of filesystem permissions. You should make sure your projects are all owned by the same user the web server runs as (often "www-data" or "apache" or "nobody" depending on the server and your distribution)

E.g:

$ chown -R www-data /var/trac

Also, check if SElinux is enabled. If so you'll need to ensure that it is configure to allow the web server process to write to the Trac projects.
