Just clean installed mythbuntu 11.10 and I'm seeing the following errors/warnings when viewing the scheduling options and details for a show.
Warning at /usr/share/mythtv/mythweb/modules/tv/detail.php, line 310:

Warning at /usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php, line 16:
!!NoTrans: Cannot modify header information - headers already sent by (output started at /usr/share/mythtv/mythweb/includes/errors.php:150)!!
