2004-11-20 16:32:23,091 ERROR [action.admin.vcs.AddRepository] Error occurred while obtaining cvs log or parsing the cvs log.
java.lang.IllegalStateException: Already have branch data: name='V_0_3_0_PATCH_0_BUILD_11_BRANCH' branchRevision='1.9.0.2' revisonNumber='1.9.2 startRevisionNumber='1.9'

This branch check failure occurs with a branch of a branch - the check to see if the child branch already exists fails as the 'parent' branch already exists.
