We migrated all the .org trac installs and svn repositories (except WP.org plugins which had been moved previously) to a new server today and upgraded from Trac 0.11 to 0.12. Unfortunately, it didn’t go so well and trac is somewhat broken (sporadic internal errors, custom queries not working, reports showing wrong data). SVN is working fine. We are working on figuring out the problem and will update this post once we have more information. Sorry for the trouble.
