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

[anonymous]

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

Traceback (most recent call last):

When i try to login to trac system, I see Trac Internal Error:

    raise TracError("The 'repository_dir' has changed, "
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)

Which 'dbname' (see DatabaseBackend#Postgresql) have you used for the first and second Trac environments ?

BTW, please preview a ticket before committing it (so that you can fix up the Wiki syntax and add verbatim blocks: {{{ }}})
