+1  Q: 

satchmo can't handle 500 error

If the quantity of the product is a Unicode character, I get UnicodeEncodeError at /add/. When I set DEBUG = False, the satchmo can't handle 500 error,it can't return an HttpResponse object, but the handler404 is ok. I find the following in the apache error log.

Why does django can not handle the 500 error page?

+1  A: 

By Django's documentation,

The default 500 view passes no variables to this template and is rendered with an empty Context to lessen the chance of additional errors

I think you should keep the same approach for your 500.html, by not extending base.html, and not even reference i18n, and instead keeping it as simple as possible.

Consider the context when you get a server error: something got wrong, and you do not know what. You may even be in a situation where not the all of the usual preconditions are fulfilled, and therefore you should maintain the page as simple as possible.
Personally, I even avoid images, relying only on some ASCII art :-)
