When I run my Mailgw script it shows 

Traceback (most recent call last):
  File "./get-support-email", line 24, in ?
    handler = getHandler([])
  File "./get-support-email", line 13, in getHandler
    return mailgw.MailGW(instance, db, options)
TypeError: __init__() takes at most 3 arguments (4 given)

Using roundup 1.4.9
