Sqlite Migrations failing

Hi all, I recently added a column change to my db but this is causing migrations to fail when run against the sqlite test db.

It's complaining about not finding a column name and then proceeding to take ages completing the rest of the tests because of a table lock issue.

The output of my travis build shows the errors https://travis-ci.org/ArthurGuy/BBMembershipSystem/builds/80595599#L788

I have the doctrine dbal library installed and I haven't had problems with other migrations like this.

Does anyone know what could be going wrong?

Thanks
