17333	Errors when reversing admin URLs when custom ModelAdmin doesn't provide model add/change URLs	Ramiro Morales	nobody	"(Originally reported [comment:41:ticket:15294 here])

Commit r16857 introduced a backward incompatible behavior of the admin app's master index and per-app index views.

The commit introduces changes in the template context building process that assume ''add'' and ''change'' permissions on models are always present when it is going to check for them. This fails with projects where these permissions might have been completely removed."	Bug	closed	contrib.admin	dev	Release blocker	fixed			Accepted	1	0	0	0	0	0
