Please make review of new changes.
Not all errors in Plist file are checked, loading broken Plist file can produce a garbage. But if an error is detected you get InvalidFileException instead of ValueError, IndexError, etc. Of course you can still get MemoryError (if read too large file) or RecursionError. |
