I installed the available version of round cube mail and get some errors:

Warning: preg_match: internal pcre_fullinfo() error -3 in /usr/share/pear/DB.php on line 762

Warning: preg_match: internal pcre_fullinfo() error -3 in /usr/share/pear/DB.php on line 631

I am using php 5 apache 2 and mysql 4.1.14

Any ideas why I get these errors?
