Rails - Nov 2012 - With streaming on, closed client connections cause Fatal Broken Pipe errors

Once we turned streaming on on www.songkick.com, we started getting these 
errors on production quite a bit. (See below)

It appears that if the client closes the connection during the rendering of 
the template, the next attempt to write a portion of the page to the 
connection will fail with a Broken Pipe error, understandably. Rails 
catches this and turns it into a ActionView::Template::Error.

So these are benign errors, but I''d like to stop them happening or
silence
them.

1. Where can we register a handler in Rails (3.2) to process template 
errors?
2. Should the StreamingTemplateRenderer be catching these broken pipe 
errors and suppressing them, perhaps with a "Request Aborted" log
line?

thanks
Dan

Error follows:
