Redmine Project Types

The method copy_issues(project) expects a Project and not a ProjectType especially at this lines:

# Reassign fixed_versions by name, since names are unique per project
if issue.fixed_version && issue.fixed_version.project == project
  new_issue.fixed_version = self.versions.detect {|v| v.name == issue.fixed_version.name}
end

Since project.is_a?(ProjectType) # -> true the assignment of issues to the fixed_version won't be executed!

This bug will probably also affect project import!
