Not ready für TYPO3 4.6
Fatal error: Call to undefined method t3lib_div::convUmlauts() in /var/www/typo/typo3conf/ext/powermail_frontend/pi1/class.tx_powermailfrontend_list.php on line 78
I think this function is no longer available in Version 4.6

Here is the solution
* Change umlaut characters to plain ASCII with normally two character target
* Only known characters will be converted, so don't expect a result for any character.
* Ã¤ => ae, Ã– => Oe
* @param string String to convert.
* @deprecated since TYPO3 4.1, will be removed in TYPO3 4.6 - Works only for western europe single-byte charsets! Use t3lib_cs::specCharsToASCII() instead!
* @return string
