Equal sign in message breaks contrib.messages when CookieStorage is used.

If you have a equal sign (=) in your message and you use the CookieStorage and you do a Redirect after the have added the message, than: the message is never displayed

I think because the equal sign is not escaped and breaks the cookie. This happens in Django 1.4.5

I can't reproduce the issue you're describing (I tried on master and on 1.4.5 and with both the CookieStorage and the default one).
Here's the code I used:

from django.contrib import messages
from django.http import HttpResponseRedirect
from django.shortcuts import render

def show_messages(request):
    if request.method == 'POST':
        messages.success(request, 'This message contains an = sign')
        return HttpResponseRedirect(request.get_full_path())
    return render(request, 'show_messages.html')


{% for message in messages %}
    <li>{{ message }}</li>
{% endfor %}
<form method="post">
    <input type="submit" value="Add message">
    {% csrf_token %}

Plug this in your urlconf somewhere and go to the page.
When you click the "add message" button, you can see that a message is added even though in contains an equal sign.

I'll close this ticket as worksforme. Please reopen it if you have more information on how to reproduce this issue.
