TYPO3 Core

When I open the "My Extensions" tab, I get the following error in the Debug Console.

PHP Warning: Missing argument 1 for tx_em_Connection_ExtDirectSoap::getExtensions() in /opt/local/apache2/vhosts/typo3dev/typo3conf/ext/em/classes/connection/class.tx_em_connection_extdirectsoap.php line 186
