[TYPO3-english] Fatal error: Class 't3lib_l10n_parser_Llxml' not found in /html/typo3/typo3_src-4.5.16/t3lib/class.t3lib_div.php

Hi,

when trying to insert a content-element I get the error:

Fatal error: Class 't3lib_l10n_parser_Llxml' not found in 
/html/typo3/typo3_src-4.5.16/t3lib/class.t3lib_div.php

I installed the extension "tan3_glider" bevore. But after deinstallaion 
an clearing all caches and temp-files, the error occured permanently...

Any idea?
