NullPointerException

[Koitharu]

After some actions (I suppose mostly after removing versions via Admin tab) Acrarium stop works with Internal server error
log

Looks like source of this error is in bug table in database: column latest_version_flavor in database is nullable, but corresponding field in the BugStats class is non-nullable.

Executing delete from bug where latest_version_flavor is null; in database solve this issue

I tried to fix it, however I'm not sure if it is the right way.
Version: 2.0.0-beta07

A bug without a latest version should never exist (see here), so your fix is not the right way. I'd need a clear reproducer to be able to work on this issue.
