What series of commands did you pass to 3.7.5 to create

This file was copied from an existing product which uses QT 4.7
libraries to populate the database. I cannot
reproduce the exact commands which resulted in this file, because it
is populated dynamically by the
software.
I found out that QT 4.7 is using the 3.6.19 SQLite library. The
databases were created using the 3.7.5 version,
so you were right about this. The database is created with a 3.7.5
version and populated with 3.6.19
I did some more testing and found out that the backup database which
SQLite 3.7.5 reports to be corrupted, is
reported OK by SQLite 3.6.19, although this backup was created by the
3.7.5 SQLite version.
I created a ASCII dump (using the .dump command) of the backup database
using 3.6.19 and this dump is
identical (except for the 'PRAGMA foreign_keys=OFF') to a dump of the
original database.
So it looks like SQLITE 3.7.5 and 3.7.15.1 (and probably all versions in
between) have a problem reading the backup file,
while 3.6.19 can read it.
I have stored a copy of the original database on
http://www.cbbio.nl/sqlite/energy.sqlite for further analysing
