I also have this problem. You can still use the installation, it appears that all except for passwords is working.
You can log in with the default 'admin' and password 'weberp', and access all/most functionality. It is only when you try to update the user password (through User Maintenance and/or Account Profile [from the top right corner by clicking username]) that the system rejects the modification. (Oh, if you have tried and failed to log in to many times the account will be blocked, you will need to unblock by updating `www_users`.`blocked` to 0, using a database administration package e.g. phpmyadmin or MySql Workbench or from the command line.
It appears to be a problem with password hashing, that causes the problem.
I have these entries in my php log.

This may be because of a php version (i.e. support for this function in php) or the php function definition has not been well defined or erroneous in the php code. I suspect a slight change in the way php handles some built in function call from the version of php that I am using to the version that the system was developed on (I am using OSX 10.6.8, which uses a bundled Apple version in a php...so library for the also bundled Apache server).
I intend to go through the code and find the function call for mcrypt_create_iv() (this is a php function and not a user defined function) and see if there is a simple fix to the issue, i.e. varying methods or syntax to call the function in php.
I only installed the system for the first time a few minutes ago, if I find a resolution I will let you know.
