Cannot create item table

[reporter]

I get this error when accessing Gregarius for the first time after running install.php:

• The item table doesn't exist and I couldn't create it! Please create it manually.
• 1 out of 11 tables could not be created!
• Creating your database schema! This should be a one-time operation, if you see this message over and over again please import your database schema manually.
• inserting some default config values...

The problem seems to be the SQL statement in _init_item(), schema.php

I am using sqlite
