If you're not experiencing those problems, then you probably don't have a proper install of WP 2.0.3
The confirmation exists because the nonce (blog/user/action/object/time key) in the form doesn't match the one on the receiving end. The same problem exists when you edit another WP user's profile. Both of those are fixed in my plugin by providing versions of the nonce create/verify functions that look for these malformed keys, and correct them, so that they match. It does NOT disable any security measures! It also fixes the slashes bug by stripping the slashes where appropriate. These fixes are the same as the fixes that have gone into
/branches/2.0.3/ ... I just made it into a plugin form.
No news on on when (or if) an updated version of WP will be out, sorry.
you may want to check out
/branches/2.0/ from SVN. That has 3 of the 4 fixes that my plugin provides (and will likely get the 4th soon... I've provided the patch for it).
