DB error on fresh install of module using sqlite

Installing File Entity 7.x-2.0-alpha1 on a sqlite3-backed site results in a critical error message. Some more details:

- Error occurs with both the 2.0-alpha1 and 2.0-dev version of File Entity.
- Error occurs whether enabling via the UI or via Drush (5.8).
- Using 7.23 core with standard installation profile. Enabling File Entity obviously requires ctools; this downloads and installs correctly beforehand
- No error when using MySQL DB.
- No error when using sqlite and upgrading from a previous version of File Entity, in my case 2.0-unstable7.
- SQlite DB is version 3
- OS is Ubuntu 12.04.2 LTS
