TYPO3 Core

on line 180 of
RteFileLinksUpdateWizard.php
the code only checks if NULL is returned from the exec_SELECTgetSingleRow function, but it looks like it returns "false" (at least in my case).
Changing line 180 to
if ($record !== NULL and $record!==false) {
lets the wizard run through

original code:
// Get the current record based on the sys_refindex information
$record = $GLOBALS['TYPO3_DB']->exec_SELECTgetSingleRow(
'uid, ' . $reference['field'],
$reference['tablename'],
'uid = ' . $reference['recuid']
);
if ($record !== NULL)
