Permalink custom structure 404 issue

[bankrate]

I have run into a weird issue where 4 digit post_id's for the following custom structure is causing a 404 Not Found.

Custom structure setting:
/%post_id%/%postname%/

Example broken URL: (4 digit post_id)
​http://www.bankaholic.com/1005/more-high-yield-checking-accounts/

Example working URL: (3 digit post_id)
​http://www.bankaholic.com/988/americanet-checking-account-is-very-rewarding/

I have tried tweaking the core to see if I could find a fix but was unable to do so. I was also unable to find similar issues by searching the docs, trac, and google.

One interesting think to note is that if you call the page with only the post_id without the postname slug it does work.

Most likely a dupe of #5305

actually, this one looks even more fun. the odds are it's getting matched as a year. :D

the short answer imo is wontfix. and use the default, yyyy/mm/dd/slug as the permalink structure

see also #9595 (closed as dup)

I changed my Custom Structure to "/%post_id%/%postname%/" using trunk. Worked right away.
