Comment 4 for bug 276144

I just got a similar OOPS. The table is different, but this may be a storm issue from the same bug.

OOPS-1060EA133:

Traceback (most recent call last):

    * Module zope.publisher.publish, line 141, in publish
      publication.handleException(
    * Module canonical.launchpad.webapp.publication, line 445, in handleException
      raise Retry(exc_info)

Retry: update or delete on table "branch" violates foreign key constraint "branchrevision__branch__fk" on table "branchrevision"
DETAIL: Key (id)=(26850) is still referenced from table "branchrevision".
