PayPal IPN Issues

[appel268576]

Hi John.

I am using the simplest of solutions, the buy now button.

I have my IPN settings activated in my Sandbox Account AND my
"notify_url" set to the same one.

http://beta.mysite.com/ipn-signal/

When i try to run a IPN from the sandbox testing tool I get an Error
500

my paypal directory was copied to my apps and is now at
mysite.apps.paypal
my urls.py includes my ipn settings

(r'^ipn-signal/', include('mysite.apps.paypal.standard.ipn.urls')),

any ideas why it would not receive the signal?

I am seeing this exact same issue.
I previously set up IPN with PHP scripts & everything was OK, but I'm
trying to use django now & specifically this module for IPN
transactions
Does it have anything to do with the dummy data sent by Paypal sandbox
(as opposed to the setup on my site) ?

I also couldn't figure out how to handle/set up the 'signals'
mentioned in the README
This code would be great if I could get it to work.
Also if anyone has a more complete example it would help a lot.
