[SOLVED] Manager/Tools/Configuration tab error in Evolution 1.0

I’m getting the same repeated error in Tools/Configuration tab of the Manager (x21):

Warning: array_keys() [function.array-keys]: The first argument should be an array in /home/xxxx/public_html/manager/actions/mutate_settings.dynamic.php on line 1283

Apache version: 2.2.10 (Unix)
PHP version: 5.2.6
MySQL version: 5.0.81-community
Operating system: Linux

Version: Modx 1.0.0
Browser/Client: Mac Camino and Safari

Upgrading Downgrading to 1.0.0 RC2 fixed it.

Update v1.02: deleting and replacing the manager directory (and backing up config file), instead of overwriting it with the new install, has fixed the problem.
