When I try to run my webserver in the production environment I just get an application error message. This is all I can find in the log: ActiveRecord::StatementInvalid /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.1/lib/active_record/ connection_adapters/sqlite_adapter.rb:274:in `table_structure' /usr/lib/ruby/gems/1.8/gems/activesupport-1.4.0/lib/active_support/ core_ext/object/misc.rb:23:in `returning' /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.1/lib/active_record/ connection_adapters/sqlite_adapter.rb:273:in `table_structure' /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.1/lib/active_record/ connection_adapters/sqlite_adapter.rb:210:in `columns' /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.1/lib/active_record/ base.rb:760:in `columns' /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.1/lib/active_record/ base.rb:768:in `columns_hash' /usr/lib/ruby/gems/1.8/gems/actionpack-1.13.1/lib/action_controller/ session/active_record_store.rb:105:in `setup_sessid_compatibility!

How can I debug this? Is there some way to figure out what the invalid statement is?
