Getting internal error when adding another project with "trac-admin project initenv "

When I try to add new project with other svn repository I get this error:

TracError: The 'repository_dir' has changed, a 'trac-admin resync' operation is needed.

If I try to run the trac-admin resync script, everything is done fine, the new created project work well, but the previous one got the same error (and again, when I run resync on the first project, it starts to work fine and the other project got the same error again)
