FWIW I have also come across this problem and here is what I've found.

The bytes reported 0x62, 0x70, 0x6c, etc., are part of the magic string "bplist" at the start of a binary property list, which NSKeyedArchiver uses by default.

A binary property list stores metadata in a trailer (i.e. at the end of the data). So if it gets truncated, the entire plist becomes unreadable.

If you want to check whether that's what has happened to you, you can use NSPropertyListReader_binary1 from Cocotron (http://code.google.com/p/cocotron/source/browse/Foundation/NSPropertyList/) to see how the file format works.

Hope this helps someone!
