Pyramid: cyrillic letters in url shows “A server error occurred. Please contact the administrator.” in debug mode

Question

I have articles with cyrillic letters in it's text and title text. The url of the article is

/%s/%s % (article.id, article.title.replace(' ', '_'))

And when I try to open this article it shows me

A server error occurred. Please contact the administrator.

Nothing about error or else. And all this in debug mode.

How to solve this problem?

Thanks!
