Articles / Twitter / TinyURL > wrong url redirection format

I have the following problem when I broadcast articles to twitter with TinyURL as URL Shortener :

The built/redirect of TinyURL doesn't match the article URL format as defined in 'Advanced settings' > 'General'.

For exemple the tinyURL doesn't redirect to :
http://mysite.com/articles/%Y/%m/%d/%alias/ as expected
but to :
http://mysite.com.com/articles/alias.html, then the displayed page is not the article post/entry but the article list...

Help welcome!
