Probably a security hole in F13?

I want to report some weird F13 behaviour:

Booting into runlevel 3 (with RHGB, appending ' 3' after RHGB). After 
boot is completed, goto on console #1.

0. Waiting some seconds
1. Very often, when typing the username, it is *not echoed* (but accepted)
2a. In this case, typing in the password, it is fully reflected :-(

------ this appears on console #1 -----------------
Fedora release 13 (Goddard)
Kernel on an i686 (tty1)

eule login: Password: testuser

[testuser at eule ~]$
------------------------  OR case 2b, username is reflected ---- 
---------------------------- and password is reflected ---------
Fedora release 13 (Goddard)
Kernel on an i686 (tty1)

eule login: testuser
Last login: Thu Apr ........... from localhost.localdomain

But: If booting into runlevel 3 *without RHGB*, or into runlevel 5, the 
described effect does not appear.

Anybode made similar experiences?
