[Paul Eggleton]

Hi Diana,

Sorry it's taken me a ridiculous amount of time to get back to you on this!

I had a chance to try your patch out today, although I had to apply it 
partially - I figured a good test would just be the email part. I installed 
rabbitmq and ensured it got started. I started the web interface and submitted 
a dummy layer, and the email sent as expected. I then tried killing my local 
SMTP server and the layer submission returned an error page, which is what 
happened previously - it looks to me as if the sending is still being done 
synchronously. The celery worker isn't reporting anything so I can only assume 
the django app is not trying to connect to it.

I've pushed just the changes I applied to a new branch here:

http://git.yoctoproject.org/cgit/cgit.cgi/layerindex-web/log/?h=paule/celery

Any idea what's going wrong? Did I mess up in applying the changes, or 
misconfigure something else? 

Thanks,
Paul
