<pre>Retitling:
Database process crashes deleting a corrupt SQLite database file (null deref)
The database files that reproduce this are inconsistent IDB databases. Probably generated from a previous DB process crash that wasn't recovered from.
When the backing store tries to read from the file, it sees things it doesn't expect, so it closes and nulls out the database handle.
Then, we create a SQLiteStatement with a null database handle, causing the crash.
Adding a null check in the right place is appropriate, and allows the database to be deleted as expected, getting the bot (or user) out of this bad state.
Now to write a test.</pre>
