While doing a POST operation on /ticket/4085, Trac issued an internal error.

Posting a comment containing "reviewed PR:2296" and "reviewed PR:2297". But PR:2297 was only just created while writing that comment and was shown as a green "new / conflicting" comment.

Actually it was probably just a typo in the PR number "2297" should have been "2287".

Still might be nice to show a better error message for non-existing PR numbers.
