previous_comments_link and next_comments_link return wrong url with PATHINFO permalinks

[FireMotion]

When using PATHINFO permalinks, previous_comments_link() and next_comments_link() return a wrong link, which renders paged comments useless.

Steps to reproduce:
Set permalinks to: /index.php/%post_id%/%postname%/

The functions return URLs similar to: /comments-page-1/#comments
This URL results in a file not found (if no rewrite rules are available, which should not be necessary if the PATHINFO permalink structure is used).

Expected URL: /index.php/comments-page-1/#comments
Manual opening the URL results in the expected/correct paged comments page.

Correct URL would be /index.php/123/post-name/comments-page-1/#comments, not the URL described.

If I set permalinks to

/index.php/%post_id%/%postname%/

And I go to a post with comments, the previous comment link points to:

http://localhost/wp/index.php/26/hello-world/comment-page-1/#comments

Which works fine. Can you clarify what your actual and expected links are?

My apologies, I now realize some information is missing:

I'm using a static page as my front page (and am not using any posts).

This is why, in my initial post, wrote: /index.php/comments-page-1/#comments, which indeed should be the expected URL (which is confirmed working, when manually entering the URL in a browser).

I'm guessing this is the cause of the problems (and it's confirmed working on other pages that are not the front page).

Ah, so index.php is missing from the comment page links on the static page homepage. Got it.

Viper007Bond: Your summary is correct.
"index.php" is missing from the comment page links, when using paged comments, a static page and PATHINFO permalinks.
