msginit doesn't work

[Chris <bbshliu@gmail.com>]

Hi everyone,

I try to use msginit to generate a po file, but it doesn't work.

msginit -l zh_CN.UTF-8

The new message catalog should contain your email address, so that users 
can
give you feedback about the translations, and so that maintainers can 
contact
you in case of unexpected technical problems.

Which is your email address?
1 a@gmail.com
2 b@gmail.com
3 bbshliu@gmail.com
4 chris@debian

Please choose the number, or enter your email address.

It stucks here.

I've examined the script /usr/lib/gettext/user-email that verifies the 
email address. It just requires something like   *@*.*   . But whatever 
a fully qualified domain name I give, it doesn't show any messages.Could 
anyone help me?
