Cannot get contents of plist files

I want to check the contents of the Info.plist file in an iPhone backup in ~/Library/Application Support/MobileSync/Backup/hash. I can quickview the file or open it in XCode and see the contents. I can also open it in Atom or TextEdit so it seems to be a plaintext encoded plist instead of one of the weird binary encoded plists. However, when I run it through hazelimporter I get the message:
