If i have a project (project a) with another project included (project b), if project a's target has a target dependency on the product of project b, I get an error when running xUnique on project a (verbose output below). If I remove the target dependency, xUnique succeeds, but the project file is corrupted, and Xcode crashes (in a recursion, apparently, trying to PBXReferenceProxy setContainer).

xUnique output on fail:
Uniquify and Sort
uniquify PBXProject
uniquify PBXGroup and PBXFileRef
uniquify XCConfigurationList
uniquify XCConfiguration
uniquify Subprojects
uniquify PBXContainerItemProxy
uniquify PBX*Target
uniquify XCConfiguration
