Call to a member function get_charset() ...

[apan_jocko]

I've glance through the forum and could not find any post with below error message. This is what I get , even with a "fresh" install of beta 2.
Can anybody shed some light on this for me ?

 PHP Fatal error: Call to a member function get_charset() on a non-object in /var/www/oakisland.se/roundcubeb2/program/include/main.inc on line

Otherwise, thanks for an excellent (be it beta) product !
