TYPO3 Core

When i show sys_log with backend module and "action: error" is selected, there is shown no output or an error message (ORA00920).
I use TYPO3 with Oracle11g (with DBAL).

Problem is located in typo3/sysext/belog/mod/index.php line 258:
// Action (type):
$where_part='';
if ($this->MOD_SETTINGS['action'] > 0) {
$where_part.=' AND type='.intval($this->MOD_SETTINGS['action']);
} elseif ($this->MOD_SETTINGS['action'] == -1) {
// $where_part.=' AND error'; - this causes the error because of a missing comperator
$where_part.=' AND error = 1';
}
