[fw-mvc] error while loading zend_filter_StripTags class

hi

i have this error on my linux server when runing a action that use StripTags

Warning: include(Zend/filter/stripTags.php) [function.include]: failed to open stream: No such file or directory in /home/vando/library/Zend/Loader.php on line 136

Warning: include(Zend/filter/stripTags.php) [function.include]: failed to open stream: No such file or directory in /home/vando/library/Zend/Loader.php on line 136

Warning: include() [function.include]: Failed opening 'Zend/filter/stripTags.php' for inclusion (include_path='/home/vando/application/../library:/home/vando/library:.:/usr/lib/php:/usr/local/lib/php') in /home/vando/library/Zend/Loader.php on line 136

Fatal error: Class 'Zend_filter_stripTags' not found in /home/vando/application/models/Vando.php on line 79


i looked at the Zend folder ...  the folder named Filter is first letter uppercase but the include statement seems use filter not Filter

how can i fix that?
