Setting "Create email address for unix user?" causes error with postfix

Install on debian with postfix.

Setting "Create email address for unix user?" to "yes" in the create virtual server screen causes the error:

"Failed to create virtual server : Missing file to open at postfix::../web-lib-funcs.pl line 1659"

That in terms leaves a mess on the server as described in bug #6 which IMHO should be reopened.

Closed (fixed)
