One of the things it breaks is nmbug. The quick and dirty fix would be to have nmbug ignore any comment lines in the dump output. There is an option to the new dump (--include=tags) which omits the config information, but it still adds a single header line. I'd be open to the idea of omitting the header line if there is no config information in the file. The other question is if the current default of including configuration information is a good idea. For the most obvious use case of backing up the user's data, it seems like the right thing to do. d
