Submit button space inclusion issue related to Python

[Malte Beckmann]

Error message is encountered when visiting a page that contains a form submit button which contains text with spaces, e.g. "sign in" (two words separated by space) versus "logout" (one word, no spaces).

Result: Instead of writing "Sign in", we have to make it one word: "Signin". The code will look like this:
{% submit_button _('Signin') 'ab_white' %}

We currently assume it's a Python related issue. Gabriel will try to replicate it in the sandbox.

Confirmed to be an "old django" bug. When doing the same tagging on sandbox, that runs on django 1.0 code, there is no problem. So expect this to go away in the 1.0 upgrade.
