Title-less Image Attachment Badly Created
|Reported by:||filosofo||Owned by:|
Create a new post. Upload a picture with no description or title. Select display thumbnail, link to page. Publish (with date-based permalinks).
The link to the attachment page becomes something like [permalink to the post][id of the attachment], which when requested, the permalink system thinks it's being asked to produce [permalink to the post][page number, where the page number is the id of the attachment].
That returns only the post, as there is no page XX for that post.
The problem seems to be that when the attachment wp_posts entry is created for an image without a title or description, post_name is given a numerical value instead of something like the sanitized filename. However, at the moment I can't figure out where that's happening.
