4279	Non-null TEMPLATE_STRING_IF_INVALID breaks admin UI	Jeremy Dunck <jdunck@…>	Adrian Holovaty	"The default admin templates include various lookups that are expected to fail under many conditions, but this only works nicely if TEMPLATE_STRING_IF_INVALID is the default ("""").

For example, the contrib.admin.templatetags.results_headers yields dictionaries that often don't have class_attribs as a key, but the related template, admin/change_list_results.html, includes this code:
{{{
<th{{ header.class_attrib }}>
}}}

A non-null-string TEMPLATE_STRING_IF_INVALID causes the code to have an invalid tag type.

I'll hopefully soon file a patch, but wanted to report the issue in the meantime."		closed	contrib.admin	dev		duplicate	admin template template_string_if_invalid		Unreviewed	0	0	0	0	0	0
