bug: cleaner error message on OptionUnsetError in initialize We got a scary traceback when a: roundup.configuration.OptionUnsetError exception was raised during tracker.init(). Capture the exception and raise a UsageError that is printed more cleanly. It now reads: Error: In tracker/config.ini - MAIL_DOMAIN is not set and has no default

def init_severity(db, cl, nodeid, newvalues):
    """Make sure severity is set on new issues"""
    if 'severity' in newvalues and newvalues['severity']:
        return

    normal = db.severity.lookup('normal')
    newvalues['severity'] = normal

def init(db):
    db.issue.audit('create', init_severity)
