When calling

tslib_eidtools::initFeUser

from a script that's called with an eID, under certain circumstances

t3lib_div::fixed_lgd_cs()

is being called. Since $GLOBALS['TSFE'] is nearly empty with eID, the method throws a fatal error because $GLOBALS['TSFE']->csConvObj and the method itself only checks for $GLOBALS['TSFE']:

} elseif (is_object($GLOBALS['TSFE'])) {
$charSet = ($GLOBALS['TSFE']->renderCharset != '' ? $GLOBALS['TSFE']->renderCharset : $GLOBALS['TSFE']->defaultCharSet);
return $GLOBALS['TSFE']->csConvObj->crop($charSet, $string, $chars, $appendString);

The fix is to check if $GLOBALS['TSFE']->csConvObj exists.

The fix is

( ! ) Fatal error: Call to a member function crop() on a non-object in /var/www/server-lokal/www.aida.de/cwe/t3lib/class.t3lib_div.php on line 593
