2894	[patch] XML Deserializer does not handle None values in Foreign Keys	andrew@…	Adrian Holovaty	"Although the XML Serializer handle_fk_field method goes out of its way to create a 'None' element if the foreign key relation is None, the Deserializer fails to handle the case.

Example: In a Model with a self-referential Foreign key which is allowed to be blank (and null), you may have entries with a blank value.  This gets mapped to the 'None' element over the wire and results in an exception when the system attempts to find the related key with primary key '', since the None element contains no text."	defect	closed	Core (Other)		normal	fixed			Unreviewed	1	0	0	0	0	0
