The headers are different because when lz4 support was added, lz4 did not provide a library to write the headers so I added custom headers. You should be able to use coredumpctl to unpack the file.
"Proper" lz4 support has been written, but lz4 upstream has trouble with keeping .so compatibility: https://code.google.com/p/lz4/issues/detail?id=147. So the question is whether to replace lz4 with something more stable or to ignore the issue and hope it doesn't happen again.
