I have my server set up to email me whenever a page throws a 404 error, and it just emailed me after I checked the stats page on a fresh 2.2.0-beta installation...
This is the error info:
Problem = www.domain.com/blog/'.$rsc_url.'/img/blank.gif
Referrer = http://www.domain.com/blog/admin.php?ctrl=stats&tab=summary&blog=2
It's looking for blank.gif (obviously) but the rsc_url hasn't been processed...
I guess this qualifies as a bug... or perhaps not...?
