Problems with SQLite3

Hi!

I've got a very strange problem. Suddenly the SQLite3 Backend stopped
working.

Example 1:

rake db:rollback

== CreateProducts: reverting

Your migration failed and you have a partially migrated database in SQLite. I would suggest dropping and recreating your test database by hand and then running your tests again.

Unfortunately, that did not help. I deleted the database and recreated
it (BTW, this is a really simple test project with just one relation),
but I still get the same error. I still cannot do rake db:rollback in
the development environment. This is the output with --trace:

** Invoke db:rollback (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:rollback
