Would reinstalling leapord fix this?
What this means is that either one of your kernel extensions or one of your login items is buggy. If you added any third-party software that wanted a password to install, or added anything to Login Items in your account pane, that could be it.
Making a new account is the usual best way to tell where the problem is. If the new account runs fine, then there is something in the extensions, login items, or preference files on that account.
