Duplicate element id`s

Further explanation follows.

When both the user login block from core and the simplenews newsletter block are on the same page, the page won't validate due to duplicate ID`s.

Here is an example:
http://validator.w3.org/check?uri=http%3A%2F%2Fwww.awareness.org.il%2Fqu...

I've tried looking in the module's code but i couldn't find where the ID is specified. Shame - I wanted to submit a patch and feel like I'm contributing.

Any help on this? I want my pages to validate :-)

Excuse the repeated posting - I'm tired. This is the right address:
http://validator.w3.org/check?uri=http%3A%2F%2Fwww.awareness.org.il%2Fwe...

The forms in the blocks don't work well when there is more then one block in the page. I am assuming that this is due to the duplicate id`s.

Of course it also doesn't pass validation.

I've read that thread but I'm not sure - Is this a Drupal core problem? Can't a module set it's own id`s?
