{{{

request from the browser (enter anything in search box).

{{{GET /admin/project/foo/?q=123}}}

I get this error

I'll be glad to have some guidance where is the best place to write the test.
Then I can work on making a fix."	Bug	closed	contrib.admin	1.9	Normal	duplicate	admin		Unreviewed	0	0	0	0	0	0
