4176	DebugLexer breaks token source (breaking django exceptions)	Chris Beaven	Adrian Holovaty	"`django.views.debug.get_template_exception_info` expects the token source to be `(origin, (start, end))`:
{{{
#!python
origin, (start, end) = exc_value.source
}}}

Malcolm's recent change in [5104] changed this to just `(start, end)` which is breaking Django's pretty exception view.
