Problems with rails 3.1

I’ve created a new app with rails 3.1
Run rake db:migrate and:

== DeviseCreateUsers: migrating

== DeviseCreateUsers: migrated (0.0000s)

rake aborted!
An error has occurred, this and all later migrations canceled:

private method `split’ called for #Arel::InsertManager:0x48fa3b39

What’s the problem?

I’m the only one with this kind of problem?
I’m using jruby, with ruby and postgres rake db:migrate is ok?
