[Rails] SQLite adaptor problem

[Nolan J. Darilek]

Recently I wrote an authentication controller, and it worked on RAILS
0.8. I didn't work on the site for a few weeks, though, and now my
authentication controller fails when used with the latest version of
Rails and ActiveRecord, both the latest stable versions and the 12-01
beta gems. Here is the error I receive:

ActiveRecord::StatementInvalid in Authentication#signup

unable to open database file: BEGIN

AuthenticationController:27 is a call to Member.save.

I'm sure the configuration is right and that I'm pointing at a valid
database because immediately before I received this error I got a
"Trying to write to read-only database," which went away when I fixed
the permissions on the file.

Any thoughts on what might be going on? What additional information
can I offer to help track this down?
