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

I had the same issue. TYPO 4.7.X had some annoying bugs, so we decided to downgrade back to 4.5.20.
 
After that adding a new content element was not working anymore.
 
Finding the offending plugin was easy:
 
[root at baspclinux ext]# fgrep "t3lib_l10n_parser_Llxml" * -R
powermail/Classes/Utility/WizIcon.php:          $localizationParser = t3lib_div::makeInstance('t3lib_l10n_parser_Llxml');
 
Our fix was to (temporary) uninstall Powermail 2.0.
