Description of problem:
https://bugzilla.redhat.com/beta2/show_bug.cgi?id=137459

Note the empty reporter field.
In the old bugzilla, we get the reporters email address.

Because of sanitizing email address for spam, if an account doesnt
have a real name, then nothing is shown. I suggest showing the email
address when no real name is there but create a
Bugzilla::Util::SanitizeEmail() function will replace for example,

foo

with 

foo_AT_bar.com

or similar.
