Sqlite3 crash due to premature call to shutdown.
calls to layout very rarely have any obvious effect,
but sometimes under odd and idiosyncratic circumstances
they do.
Called shutdown after the destroy was executed, but destroy does
not immediately destroy the windows, thus does not immediately
finalize all compiled sql statements and close all database
connections. You have to wait for all the windows to be destroyed.
Again, a rare crash except under certain special circumstances.
