The .htaccess file which you should use comes with your MediaWiki package. In MediaWiki 1.20.2 this file does not even look similar to what you posted. Instead, this is the content of this file:

 RewriteEngine On	RewriteCond %{QUERY_STRING} \.[^\\/:*?\x22<>|%]+(#|\?|$) [nocase] RewriteRule. - [forbidden] 
 * 1) Protect against bug 28235

Use that file (which by the way should be secure). Does that file work? I would expect that to be the solution.
