Issue Description

Importing a tar.xz archive as a container fail with the following error :
Error: writing blob: layer 0 (blob "sha256:57eca825bd922bd6aa59c30ac95be594144816b3951caefa2cf0be2d86db12d2"/""/"sha256:ebccf21abea5bba2d53df5158901c325b33a5cb1a17c44ddd6cc97c6036a9dcc") does not match config's DiffID "sha256:57eca825bd922bd6aa59c30ac95be594144816b3951caefa2cf0be2d86db12d2"
 
I tested with an archive that the size is ~45MB without problem.
