Post paging stopped working since WP3.0

Hi,

I just realized that the upgrade to WP3.0 went fine except for my post paging. Indeed I use the <!–nextpage–> tag in some of my posts to split my post in multiple pages.

Till 2.9.2 it was working fine, and :

https://www.mysite.com/subdir/mypost was referring to page 1 of mypost
https://www.mysite.com/subdir/mypost/2 was referring to page 2,
https://www.mysite.com/subdir/mypost/3 was referring to page 3, etc

Since 3.0, https://www.mysite.com/subdir/mypost/2 (or any other page) redirects to the first page of the post, e.g :

https://www.mysite.com/subdir/mypost

Although I saw there was a fix for the post paging in 3.0.1, I am not sure this aspect is covered.

Could anyone provide me some hints ?

Thanks !
Bruno
