`ring-sample.sqlite/init-db!` only works if I `mkdir data` first?

I just played around with the ring-sample and everything worked fine until I clicked on "Records in the SQLite database" on the main page. This led to the following stack trace in the shell:

["select * from characters order by name"]
Initializing SQLite database
#<SQLException java.sql.SQLException: path to 'data/characters.db': '/home/dmta/clojure/ring-sample/data' does not exist>

...

Everything worked fine when I did mkdir data in the ring-sample root directory. I don't know if there's something wrong with my setup (missing write access or something) so that the DB driver is unable to create the directory itself but at least this report may be of help to others experiencing the same problem.
