The “first_time” just means that’s the first time the task is being invoked in this rake run, I believe. Doesn’t mean it thinks you’re running migrations for the first time ever.
I encountered this error with a plugin that had not been upgraded to be compatible with Rails 2.x. I would recommend running rake --trace again, but then look at the call stack that gets dumped to figure out exactly which task is causing this error, and perhaps what plugin may or may not be related.
