There is a HTTP 500 error sometimes because of undefined locale setting in current session.

For some reason there is a possibility for locale setting to be undefined in the session which results in following error:

    "{{ url_for('design.static', filename='vendor/cldr/main/' + session['locale'] + '/numbers.json') }}",

I would suggest instead of trying to reproduce this (as it seems mostly Internet Explorer related), to fix this here:
Modifying session['locale'] to:

session['locale'] if session['locale'] else 'sensible_default'

as the problem stems from session['locale'] sometimes being None.
