Running 'package-install-file' on a tar file might throw a 'Wrong type argument: arrayp, nil' error from 'tar--check-descriptor’. The problem comes from assumptions made by 'package--description-file' and tar-mode about the filenames contained in the tar file. I’ve written a detailed description of the error and root cause here <https://github.com/ajrosen/bookmarks-menu/discussions/2> .
I propose adding a 'condition-case' to 'package-install-file' to return a friendly message.
