Running latest Drupal v6.22 on Apache 2.2.15 w MySQL v5.1.47.

Upgraded to PrivateMsg from rc version to newest release. While I am able send pms and notification works, whenever the user views the new pms they get a blank screen and this error is in my Apache log:

[Tue Nov 01 10:49:47 2011] [error] [client 65.204.100.130] PHP Fatal error: Cannot redeclare theme_privatemsg_list_field() (previously declared in /var/www/htm

Any help or hints are appreciated.
