If I checked correctly this patch changed the on disk representation of 
NSData for archiving on 64bit systems. You changed the encoding of 
length from unsigned int to NSUInteger and if the underlying archiver 
doesn't take care of this (Richard, is this the case? Then this mail is 
pointless), this will result in a different representation. Normally we 
have to increase the version number for the class to handle such a 
change and provide different decoding paths for the different versions.
