25467	Excluding an object with no ID excludes everything.	Stavros Korokithakis	Jacob Walls	"This behaviour is surprising:


{{{
In [26]: UserAlias.objects.filter(alias=""foo@example.com"")
Out[26]: [<UserAlias: foo@example.com>]

In [27]: UserAlias.objects.filter(alias=""foo@example.com"").exclude(user=User())
Out[27]: []
}}}

The exclude should have no effect in this case, it should not exclude every user."	Bug	closed	Database layer (models, ORM)	1.8	Normal	fixed			Accepted	1	0	0	0	0	0
