We are using redmine trunk revision 1645 on a centOS 5.2 server.
mysql 5.0.44
ruby 1.8.7
rails 2.1.0

When we move an issue from one project to another, the category is lost on the issue even though the category exists in both projects.

This is what shows in the logs for the move (X's replace sensitive data):
