--non-interactive seems not to work as expected

Hi,
I stumbled upon a misbehavior of the svn client. Providing http basic auth over the --non-interactive option, does not work

        svn checkout --non-interactive --no-auth-cache --username <username> --password <Password> <URL>

> svn: E170001: Unable to connect to a repository at URL 'http://xxx'
> svn: E170001: OPTIONS of 'http://xxx': authorization failed: Could not authenticate to server: rejected Basic challenge (http://xxx)
>
> v1:tmp zeph$ svn --version
> svn, version 1.7.8 (r1419691)
> compiled Jan 3 2013, 13:26:29
>
> on OsX 10.7.5 with Homebrew

either with…

> svn: OPTIONS of 'http://xxx': authorization failed: Could not authenticate to server: rejected Basic challenge (http://xxx)

on an Amazon's linux machine

> root_at_ip-10-48-162-xxx:~# svn --version
> ]svn, version 1.6.6 (r40053)
> compiled Jun 5 2011, 14:52:04

> root_at_ip-10-48-162-xxx:~# uname -a
> Linux ip-10-48-162-xxx 2.6.32-302-ec2 #6-Ubuntu SMP Sat Feb 6 19:33:14 UTC 2010 i686 GNU/Linux

some other people seem to have experienced the same…

Can you confirm it? I'm proceeding in checking out the source code to have a look...
