ValueError: invalid literal for int() with base 10: '700/'

The issue can be reproduced on navigating to the URL (​https://trac-hacks.org/timeline?from=2010-05-09T21).

There's an entry in the database for attachment b.php~ on resource ticket #700/: ​https://trac-hacks.org/search?q=b.php%7E

I'm guessing the attachment doesn't exist, but the problem could also be that the parent resource id 700/ doesn't exist and is an invalid resource id.
