SystemStackError (stack level too deep) when creating new AR

Hi. I have a problem with very deep calls, causing SystemStackError.

The logs are on Parked at Loopia

It scares me, because I don't understand it's cause, and I fear it may strike on production (in case it disappears in development :wink: )

Tests are passing without disturbance. Maybe it's because of webrick, as it creates almost half of the call-trace? I plan to use fastcgi later.

I got this odd error when using the console, however a restart of the console fixes it. Any thoughts?

Note that the stack level is only like 20 deep, and I have tested it and it can go (typically) to thousands deep. So something must be using up tons of stack space?
