internal error on user creation with account manager and notification "gaierror: [Errno -2] Name or service not known"

[anonymous]

Hello,

this happens when creating new user with 'user creation notification' enabled. The user is created, however. When "Get notified of new account creation" is disabled, everything works fine. Maybe it is a good point to tell, that notification emails about ticket changes are working well, too.

Hoe the choosen hack is correct.
