Redmine

Hi,

I have trouble migrating a Mantis database to Redmine. I only uise 1.0.3 because the migration process started some months ago, and due to administrative reasons, I can't keep up with the latest version each time.
I have the infamous latin1/UTF-8 issue with mantis, so the mantis database was converted into a latin1 one (http://blog.meissner.it/migrating-from-mantis-to-redmine/). When restarting the migration, I got an error:

Migrating projects.

It started migrating the first project, but the second one failed.

rake script/about gave this:

Is there something I should upgrade? (perhaps upgrading to 1.1 ?)
