http 404 renders home page instead of page not found template

[pleini]

I have problems with some 404 URLs, that are not rendering the page_not_found template but the home page template instead.

Normal URLs that don't exist

like

/this-page-does-not-exist

 are redirected to my 404 page without any problems.

But for URLs like 

/cool-page%20abc
/page&=123
/pagename'A

the home page is rendered. But when i am checking the webdeveloper console, the return code is 404

Do i miss some configuration? 

Thank you

This might be the same problem as in issue #55.
