Bug#381861: Asterisk user and group aren't being created, breaks installation on fresh systems

[neoXite]

Package: asterisk-config
Version: 1.2.10.dfsg-2

The asterisk user and group aren't being created by asterisk-config on a Debian machine
not already having a previous version of the Asterisk packages (ie 1.2.7.1.dfsg-3).
Upgrading an older version to 1.2.10.dfsg-2 works fine, fresh installs (no upgrade)
of 1.2.10.dfsg-2 however are broken.

Best regards,
