Programming by permutation is never a good strategy.
render_to_response() takes 4 arguments[1]
render_to_response(template_name[, dictionary][, context_instance][, mimetype])
In your 'working but no idea why' example, you are providing a Context
as the dictionary, which works as contexts are dict-like in their
nature, and a RequestContext (with no values) as the context. The
contents of the supplied dictionary are merged* into the context.
A typical view using RequestContext and render_to_response should look
like this:
def someview(request):
ctxt = RequestContext({
'hello': 'world',
})
return render_to_response('sometemplate.html', context_instance=ctxt)
It is therefore pointless to provide a Context as the dictionary
parameter, and an empty RequestContext as the context parameter.

* Not really. Contexts actually have a stack of dictionaries, and
works down through the stack to resolve a variable used in a template.
It is easier to think of it as merging them though.
