I'm using the update_profile_image API call which is now working wonderfully. The problem I'm having is the corresponding profile_image_url attribute I'm pulling from /users/show/<username>.xml is taking hours to update (upwards of 12 it seems). I did notice that the /<username>.xml reflects this update immediately. This is apparent if you're using a twitter client (say tweetie or twitteriffic). If a user updates their profile image these apps are showing blank/empty images because the API is still returning the old profile image url, which no longer points to a valid file.
I've been following and commenting on twitter issues #648, #637 and $497, but haven't gotten feedback. Any word on what's going on here? +Clint
