I based my code on the **Creating an Upload Task for a Multi-Part Request, with Progress**, example. When I construct AFURLSessionManager with **[NSURLSessionConfiguration defaultSessionConfiguration]]** everything is working as expected. However when I try to use **[NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:[[NSUUID UUID] UUIDString]]]** to enable background upload, the application crashes with  EXC_BAD_ACCESS in the AFNetworking library. I have attemped to ask for help/insight on stackoverflow without success: http://stackoverflow.com/questions/34048865/afurlsessionmanager-crashes-with-exc-bad-access \r\n\r\nHas anyone else run into this issue before? It seems more and more like a bug. See stackoverflow post for complete code"}}
