Redmine

I get this error when i try to automate auto-repository creation

reposman.rb:148: [BUG] Segmentation fault
ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-linux]
Aborted (core dumped)

This is the format of the command i use.
ruby /var/www/rails_apps/redmine/extra/svn/reposman.rb --redmine redmine.example --svn-dir /var/svn --owner www-data --url http://svn.example.com/svn/

I am using Rails 2.1.2

Any ideas how to fix it?
