TYPO3 Core

If I search in the frontend and have indexed no english pages (L=2) everything is fine. If english pages are indexed the search engine brings an error for each search result it finds for the searchword. It is:

Warning: Wrong parameter count for preg_replace() in /typo3_src-4.0beta3/typo3/sysext/indexed_search/pi/class.tx_indexedsearch.php on line 1990

Warning: Cannot modify header information - headers already sent by (output started at /typo3_src-4.0beta3/typo3/sysext/indexed_search/pi/class.tx_indexedsearch.php:1990) in /typo3_src-4.0beta3/typo3/sysext/cms/tslib/class.tslib_fe.php on line 2703

Again: If only the german page is indexed the result is fine.
At this time there is an index on the english version the error occurs.

Running RealUrl V 1.1.0
L=0 is german
L=2 is english
L=1 was german, then deleted
