Loading a corrupted file with a known extension
should raise a runtime exception.
The error condition is similar to an unknown
type (file extension). When a reader is identified as
knowing the file extension, it tries to load. If it
raises an exception, the system should try to identify
another reader that knows about that file extension.
If they all fail, we raise a runtime exception stating
that no reader was found for this file.
