What you describe above does not match the traceback below. You say you are
doing a render_to_reponse but the traceback shows a 404 (page not found) is
being generated, that is indicated by these lines:
File "/usr/lib/python2.5/site-packages/django/views/defaults.py", line 79,

However attempting to render your 404 template is raising an exception, this
is indicated here:

Based on where that error is coming from it appears your 404 template is
attempting to {% blocktrans %} a string including the variable 'lng'.
However, your 404 template is rendered with an empty context so the attempt
to lookup 'lng' in the context fails and generates the KeyError. (The fix
for that is to code your 404 template so that it does not rely on anything
being in the context.)
(How all of this is connected to what you've got in your <img> tag is a bit
of a mystery. The template you are mentioning, though, is not involved in
the error you have pasted, unless it's your 404 template.)
