Comment 3 for bug 159223

Ok, I'm uploading 2007.0.alpha5-2 that have a fix for this.

Note that the fix is not perfect. In fact these actions from any installation of schooltool will get your database moved out the way:

* purge schooltool (but don't remove the database)
* re-install

(The alternative is to not move the database out the way on purged installations with databases. Which is the behaviour this bug tries to fix.)
