Though NSArchiver says this scenario would produce an exception,
NSKeyedArchiver does not seem to do the same (the documentation
doesn't say what will happen and a quick test with an NSBezie

I was building a very simple drawing application, but met problems
when reading the file saved by my application.
The two functions as to archiving/unarchiving are as follows:
