Description (last modified by Christian Boos)


  • Reorganizing project
    • Exported 2 svn repositories, server and client
    • Created new svn repository
    • Created 2 svn folders in new repository, server and client
    • Did import into server and client folders
  • Changed trac.ini to point to new repository, then did resync
  • Browsed to project Timeline to look at changesets
  • When I tried browse to changeset [1], got an internal error
  • Browsing to other changesets worked fine
    • Changeset [2] picked up the new server folder
    • Changeset [3] picked up the new client folder
    • Changeset [4] does not exist ??
    • Changeset [5] picked up import into server folder
    • Changeset [6] picked up import into client folder
  • I searched tickets for "changeset NoneType split" with no hits
  • Search for "changeset NoneType" hit an unrelated ticket
