subversion can't checkout,rejected basic challenge

[ray]

First read: https://bugs.launchpad.net/ubuntu/+source/subversion/+bug/473139

Then I renamed the .gnome2/keyrings folder. (just temporary to test if this works from there onwards) Like someone here suggested: http://netbeans.org/bugzilla/show_bug.cgi?id=177482

The checkout from a https subversion repository still fails.

- Subversion ignores the --username and --pasword parameters. (It prompts again for the password of the https realm even if the login credentials were provided.)
- It seems to rely on Gnome Keyring although it shouldn't (in my opinion)
- Since the client itself is broken all GUI tools i tried also don't work.

In short: Subversion is not functional at all for a https repository. I suppose this hasn't been fixed ever since 2009. And since nobody cares about bugs from 2009 - this is 2012.
